class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>In the very early stages of pregnancy, implantation occurs when the fertilised egg attaches to the endometrium. Implantation occurs around the third week of pregnancy and is usually completed around 12 days after fertilisation. Changes that occur in a woman&#8217;s body during implantation include back pain, changes in the amount and nature of discharge, and implantation bleeding. Changes in basal body temperature, absence of menstruation and constipation can also be observed, but should be noted as they vary from person to person. The definitive symptom of pregnancy is the absence of menstruation, and if menstruation does not start after a delay of about a week from the expected start of the period, it is recommended to check with a pregnancy test.\n<\/p><\/div>\n\n\n\n<div class=\"toc\">\n\t<ul>\n\t\t<li><a href=\"#c1\">What is the very early stage of pregnancy?<\/a>\n\t\t\t<ul>\n\t\t\t\t<li><a href=\"#c1-1\">Differences between early and very early pregnancy<\/a>\n\t\t\t\t\t<ul>\n\t\t\t\t\t\t<li><a href=\"#c1-1-1\">How to count the number of weeks of pregnancy<\/a>\n\t\t\t\t\t\t\t<ul>\n\t\t\t\t\t\t\t\t<li><a href=\"#c1-1-1-1\">How to count from the day of ovulation<\/a><\/li>\n\t\t\t\t\t\t\t\t<li><a href=\"#c1-1-1-2\">How to count from the first day of the last menstrual period<\/a><\/li>\n\t\t\t\t\t\t\t\t<li><a href=\"#c1-1-1-3\">Ultrasonography to confirm<\/a><\/li>\n\t\t\t\t\t\t\t<\/ul>\n\t\t\t\t\t\t<\/li>\n\t\t\t\t\t<\/ul>\n\t\t\t\t<\/li>\n\t\t\t\t<li><a href=\"#c1-2\">When is the very early stage of pregnancy?<\/a><\/li>\n\t\t\t<\/ul>\n\t\t<\/li>\n\t\t<li><a href=\"#c2\">What is fertilisation?<\/a>\n\t\t\t<ul>\n\t\t\t\t<li><a href=\"#c2-1\">When is fertilisation due?<\/a><\/li>\n\t\t\t\t<li><a href=\"#c2-2\">Changes that occur in a woman&#8217;s body when fertilisation occurs<\/a>\n\t\t\t\t\t<ul>\n\t\t\t\t\t\t<li><a href=\"#c2-2-1\">Lumbago<\/a><\/li>\n\t\t\t\t\t\t<li><a href=\"#c2-2-2\">Headaches<\/a><\/li>\n\t\t\t\t\t\t<li><a href=\"#c2-2-3\">Drowsiness<\/a><\/li>\n\t\t\t\t\t<\/ul>\n\t\t\t\t<\/li>\n\t\t\t<\/ul>\n\t\t<\/li>\n\t\t<li><a href=\"#c3\">What is implantation?<\/a>\n\t\t\t<ul>\n\t\t\t\t<li><a href=\"#c3-1\"When is implantation due?<\/a><\/li>\n\t\t\t\t<li><a href=\"#c3-2\">Changes that occur in a woman&#8217;s body during implantation<\/a>\n\t\t\t\t\t<ul>\n\t\t\t\t\t\t<li><a href=\"#c3-2-1\">Lumbago<\/a><\/li>\n\t\t\t\t\t\t<li><a href=\"#c3-2-2\">Vaginal discharge<\/a><\/li>\n\t\t\t\t\t\t<li><a href=\"#c3-2-3\">Implantation bleeding<\/a><\/li>\n\t\t\t\t\t\t<li><a href=\"#c3-2-4\">Changes in basal body temperature<\/a><\/li>\n\t\t\t\t\t\t<li><a href=\"#c3-2-5\">Menstruation is not occurring<\/a><\/li>\n\t\t\t\t\t<\/ul>\n\t\t\t\t<\/li>\n\t\t\t<\/ul>\n\t\t<\/li>\n\t\t<li><a href=\"#c4\">What are the definitive symptoms of pregnancy?<\/a><\/li>\n\t\t<li><a href=\"#c5\">How to distinguish between very early symptoms and menstruation<\/a><\/li>\n\t\t<li><a href=\"#c6\">Is it true that you can tell from fertilisation to implantation by the state of the discharge?<\/a>\n\t\t\t<ul>\n\t\t\t\t<li><a href=\"#c6-1\">Amount of discharge<\/a><\/li>\n\t\t\t\t<li><a href=\"#c6-2\">Colour of the discharge<\/a><\/li>\n\t\t\t\t<li><a href=\"#c6-3\">Smelling of discharge<\/a><\/li>\n\t\t\t<\/ul>\n\t\t<\/li>\n\t\t<li><a href=\"#c7\">Various signs that the body and mind produce in the very early stage of pregnancy<\/a><\/li>\n\t\t<li><a href=\"#c8\">If you find out you are pregnant<\/a>\n\t\t\t<ul>\n\t\t\t\t<li><a href=\"#c8-1\">Visit a hospital<\/a><\/li>\n\t\t\t\t<li><a href=\"#c8-2\">Submit a Pregnancy Notification Form and receive a Maternal and Child Health Handbook<\/a><\/li>\n\t\t\t\t<li><a href=\"#c8-3\">Consider NIPT<\/a><\/li>\n\t\t\t<\/ul>\n\t\t<\/li>\n\t\t<li><a href=\"#c9\">What to look out for when you find out you are pregnant<\/a>\n\t\t\t<ul>\n\t\t\t\t<li><a href=\"#c9-1\">Lifestyle<\/a><\/li>\n\t\t\t\t<li><a href=\"#c9-2\">Threatened miscarriage<\/a><\/li>\n\t\t\t<\/ul>\n\t\t<\/li>\n\t\t<li><a href=\"#c10\">Summary<\/a><\/li>\n\t\t<li><a href=\"#qa\">FAQs about the very early stage of pregnancy<\/a><\/li>\n\t<\/ul>\n\t<button class=\"toc_more\">Open the table of content<\/button>\n<\/div>\n\n\n<p style=\"width:100%;max-width:300px;margin:0 auto;\"><a href=\"\/nipt\/\" class=\"content-bnr about\"><img decoding=\"async\" src=\"\/nipt\/wp-content\/themes\/hiro_nipt\/img\/banner\/nipt02pc.png\" alt=\"\u30c0\u30a6\u30f3\u75c7\u306f\u751f\u307e\u308c\u308b\u524d\u306b\u308f\u304b\u308a\u307e\u3059\u304b\uff1f\"><\/a> <\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"c1\"><span class=\"ez-toc-section\" id=\"What_is_the_very_early_stage_of_pregnancy\"><\/span>What is the very early stage of pregnancy?<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p>When is the very early of pregnancy defined?

This is the period during which the egg and sperm are fertilised and implantation takes place, but pregnancy cannot be confirmed.<\/p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-full\"><img decoding=\"async\" width=\"600\" height=\"400\" src=\"\/nipt\/wp-content\/uploads\/2021\/12\/79ff0952b96c20a7da3067c94718cebd.png\" alt=\"\u598a\u5a20\u8d85\u521d\u671f \u6388\u7cbe\" class=\"wp-image-21014\"\/><\/figure><\/div>\n\n\n<h4 class=\"wp-block-heading\" id=\"c1-1-1\">How to count the number of weeks of pregnancy<\/h4>\n\n\n\n<p>There are two ways of counting the number of weeks of pregnancy: counting from the day of ovulation, counting from the last menstrual period, or estimating from a hospital ultrasound scan.<\/p>\n\n\n\n<h5 class=\"wp-block-heading\" id=\"c1-1-1-1\">How to count from the day of ovulation<\/h5>\n\n\n\n<p>The day of ovulation is counted as 2 weeks 0 days of pregnancy.<\/p>\n\n\n\n<h5 class=\"wp-block-heading\" id=\"c1-1-1-2\">How to count from the first day of the last menstrual period<\/h5>\n\n\n\n<p>The first day of menstruation is counted as 0 weeks 0 days of pregnancy. This method assumes that the menstrual cycle is 28 days, so if the menstrual cycle deviates significantly from 28 days, there will also be a significant deviation in the number of weeks of pregnancy.<\/p>\n\n\n\n<h5 class=\"wp-block-heading\" id=\"c1-1-1-3\">Ultrasonography to confirm<\/h5>\n\n\n\n<p>As counting from the day of ovulation or from the last menstrual period often results in a discrepancy in the number of weeks of pregnancy, in most cases the fetal cephalic length (length from the tip of the foetus&#8217; head to the hips) is measured by ultrasound at 8-11 weeks of pregnancy to determine the number of weeks of pregnancy and the expected delivery date.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"c1-2\"><span class=\"ez-toc-section\" id=\"When_is_the_very_early_stage_of_pregnancy\"><\/span>When is the very early stage of pregnancy?<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p>The very early stages of pregnancy refer to the second to third week of pregnancy. The approximate period is from the last menstrual period until pregnancy is established, from fertilisation to implantation. There is no medical\/medical terminology for &#8216;early pregnancy&#8217;. However, it is a very important period for the baby&#8217;s growth and development, and many women notice changes in their bodies, so it is a time to pay attention.<\/p>\n\n\n\n    <a href=\"\/nipt\/pregnancy-week\/\" class=\"blog-card\">\n      <div class=\"blog-card-content\">\n          <div class=\"blog-card-title\">\u598a\u5a20\u9031\u6570\u306e\u6570\u3048\u65b9\u3068\u51fa\u7523\u4e88\u5b9a\u65e5\u306e\u6b63\u3057\u3044\u8a08\u7b97\u65b9\u6cd5\u3010\u533b\u5e2b\u76e3\u4fee\u3011 <\/div>\n          <div class=\"blog-card-excerpt\">\u9593\u9055\u3044\u3084\u3059\u3044\u598a\u5a20\u9031\u6570\u3068\u51fa\u7523\u4e88\u5b9a\u65e5\u3092\u6b63\u3057\u304f\u7406\u89e3\u3057\u3001\u5b89\u5168\u3067\u4e0d\u5b89\u306e\u306a\u3044\u598a\u5a20\u30fb\u51fa\u7523\u3092\u884c\u3046\u305f\u3081\u306e\u30b5\u30dd\u30fc\u30c8\u60c5\u5831\uff08\u51fa\u7523\u4e88\u5b9a\u65e5\u304c\u4e00\u76ee\u3067\u5206\u304b\u308b\u30ab\u30ec\u30f3\u30c0\u30fc\u4ed8\uff09\u598a...<\/div>\n      <\/div>\n    <\/a>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"c2\"><span class=\"ez-toc-section\" id=\"What_is_fertilisation\"><\/span>What is fertilisation?<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p>There are two important key words that describe the very early stages of pregnancy. They are fertilisation and implantation. First, fertilisation is explained in detail.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"c2-1\"><span class=\"ez-toc-section\" id=\"When_is_fertilisation_due\"><\/span>When is fertilisation due?<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p>Fertilisation occurs at the time of ovulation, about two weeks after the last menstrual period. Fertilisation occurs when a sperm enters an ovulated egg after sexual intercourse with the opposite sex.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"c2-2\"><span class=\"ez-toc-section\" id=\"Changes_that_occur_in_a_womans_body_when_fertilisation_occurs\"><\/span>Changes that occur in a woman&#8217;s body when fertilisation occurs<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p>When do physical changes occur after sexual intercourse? Once fertilisation has taken place, the woman&#8217;s body undergoes changes, albeit gradually. It is a small set of symptoms and physical changes that some people do not notice. Knowing these very early pregnancy symptoms can help you recognise the signs of pregnancy earlier and be aware of your physical condition. Here are three typical body changes that are easy to notice after conception, based on clinical research.<\/p>\n\n\n\n<h4 class=\"wp-block-heading\" id=\"c2-2-1\">Lumbago<\/h4>\n\n\n\n<p>After sexual intercourse, back pain is more likely to be felt when fertilisation is established. This is because the endometrium changes under the influence of a change in the balance of female hormones. The endometrium becomes thicker and softer in order for the fertilised egg to implant. Some people feel this change as discomfort or back pain in the lower back. Many people do not notice this change because the symptoms are not very different from those of menstruation.<\/p>\n\n\n\n<h4 class=\"wp-block-heading\" id=\"c2-2-2\">Headaches<\/h4>\n\n\n\n<p>Headaches may be perceived as a result of female hormones altered by fertilisation. Progesterone, one of the female hormones, has the effect of widening blood vessels. When the blood vessels in the brain widen, they stimulate the nerves in the brain, which can cause headaches. The headaches experienced as a result of hormonal imbalance can range from not being as bad as usual to being painful enough to require medication.<\/p>\n\n\n\n<h4 class=\"wp-block-heading\" id=\"c2-2-3\">Drowsiness<\/h4>\n\n\n\n<p>Many women feel drowsy after fertilisation. The balance of female hormones changes and the hormone progesterone increases. Progesterone has the following functions<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Continuing pregnancy<\/li>\n\n\n\n<li>Raise the temperature<\/li>\n\n\n\n<li>Intensifies drowsiness<\/li>\n<\/ul>\n\n\n\n<p>As a result, you are more likely to feel sleepy. If you feel sleepier than usual, even though you&#8217;ve had a good night&#8217;s sleep, you may be pregnant.<\/p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-full\"><img decoding=\"async\" width=\"600\" height=\"400\" src=\"\/nipt\/wp-content\/uploads\/2021\/12\/cc729d89bc62409cce3423de3b9bd9c2.png\" alt=\"\u598a\u5a20\u8d85\u521d\u671f \u7740\u5e8a\u6642\u671f\u306b\u5973\u6027\u306e\u4f53\u306b\u8d77\u3053\u308b\u5909\u5316\" class=\"wp-image-21017\"\/><\/figure><\/div>\n\n\n<h2 class=\"wp-block-heading\" id=\"c3\"><span class=\"ez-toc-section\" id=\"What_is_implantation\"><\/span>What is implantation?<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p>After fertilisation, the sperm and egg take about one week to ten days to reach the uterus. The fertilised egg reaching the uterus and attaching to the endometrium is called &#8216;implantation&#8217;.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"c3-1\"><span class=\"ez-toc-section\" id=\"When_is_implantation_due\"><\/span>When is implantation due?<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p>Ovulation occurs about two weeks after the last menstrual period. Intercourse takes place at that time and the fertilised egg takes between one week and ten days to implant. The approximate time of implantation is around the third week of pregnancy. If there are no implantation problems, implantation is considered to be complete approximately 12 days after the fertilised egg is formed.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"c3-2\"><span class=\"ez-toc-section\" id=\"Changes_that_occur_in_a_womans_body_during_implantation\"><\/span>Changes that occur in a woman&#8217;s body during implantation<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p>In addition to fertilisation, a woman&#8217;s body undergoes many changes during implantation. This section describes the characteristic physical changes that occur during implantation.<\/p>\n\n\n\n<h4 class=\"wp-block-heading\" id=\"c3-2-1\">Lumbago<\/h4>\n\n\n\n<p>Back pain may be experienced not only after fertilisation, but also at the time of implantation. Clinical studies have shown that implantation causes the fertilised egg to develop, which changes the endometrium and may cause back pain.<\/p>\n\n\n\n<p>In addition, implantation releases a hormone called relaxin. Lyraxin is a hormone that helps to soften the pelvic area in preparation for childbirth. Due to the effects of thyraxine, back pain may also be present in the very first trimester of pregnancy. This phenomenon has been confirmed by clinical studies.<\/p>\n\n\n\n<p>Pain at the time of implantation is called implantation pain. Back pain is one of the most common symptoms and is sometimes referred to as implantation back pain. Clinical studies have shown that implantation back pain is a symptom specific to early pregnancy.<\/p>\n\n\n\n<h4 class=\"wp-block-heading\" id=\"c3-2-2\">Vaginal discharge<\/h4>\n\n\n\n<p>The discharge changes in quantity and consistency in accordance with the secretion of the hormone oestrogen. When fertilisation occurs, the amount of oestrogen increases and the volume of the discharge tends to increase. In addition, the nature of the discharge changes during the time of implantation. The reason for this is that implantation changes the vaginal pH. You may notice that the discharge is different from usual, for example, it may be more dry or sticky.<\/p>\n\n\n\n<h4 class=\"wp-block-heading\" id=\"c3-2-3\">Implantation bleeding<\/h4>\n\n\n\n<p>Implantation bleeding is a common symptom that tends to occur after implantation. When the fertilised egg attaches to the endometrium, the endometrium can become damaged. This can cause bleeding for a short period of time, around one or two days.<\/p>\n\n\n\n<p>As only one in four women are aware of implantation bleeding, it may not even be noticed.<\/p>\n\n\n\n<h4 class=\"wp-block-heading\" id=\"c3-2-4\">Changes in basal body temperature<\/h4>\n\n\n\n<p>Those who measure basal body temperature may notice unusual changes in basal body temperature, which may indicate fertilisation and implantation. According to clinical research, changes in basal body temperature are an important indicator of early pregnancy.<\/p>\n\n\n\n<p>Normally, the body temperature drops 3-4 days before menstruation and menstruation occurs. However, if implantation is taking place, the body temperature remains high and menstruation is delayed. If the temperature remains high after the expected start of menstruation, the possibility of pregnancy is high. This change in basal body temperature has been confirmed by clinical studies.<\/p>\n\n\n\n<h4 class=\"wp-block-heading\" id=\"c3-2-5\">Menstruation is not occurring<\/h4>\n\n\n\n<p>The most definitive symptom may be the absence of a period. For those who normally have regular periods, the chances of fertilisation and implantation are very high if the period does not start until about a week later than the expected start of the period. This symptom has been identified in clinical studies as an early sign of pregnancy.<\/p>\n\n\n\n<p>In addition to this, it is important to note that people who have had good bowel movements before their period may be prone to constipation when pregnant, or may experience slight changes in their physical condition, like something out of the ordinary.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"c4\"><span class=\"ez-toc-section\" id=\"What_are_the_definitive_symptoms_of_pregnancy\"><\/span>What are the definitive symptoms of pregnancy?<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p>As has been explained, a number of symptoms may occur in the very first trimester of pregnancy, including implantation pain and discharge.<\/p>\n\n\n\n<p>On the other hand, some women do not show any particular symptoms. There are no clear criteria such as &#8216;when to expect these symptoms&#8217; if you are pregnant, so do not worry if you do not have any symptoms.<\/p>\n\n\n\n<p>However, one definite symptom of pregnancy can be the absence of a period.<\/p>\n\n\n\n<p>If your period is about a week later than the expected start of your period, we recommend checking a pregnancy test.<\/p>\n\n\n\n    <a href=\"\/nipt\/pregnancy-test\/\" class=\"blog-card\">\n      <div class=\"blog-card-content\">\n          <div class=\"blog-card-title\">\u598a\u5a20\u691c\u67fb\u85ac\u306e\u6b63\u3057\u3044\u4f7f\u3044\u65b9\u3068\u9069\u5207\u306a\u30bf\u30a4\u30df\u30f3\u30b0\u3068\u306f\u3010\u533b\u5e2b\u76e3\u4fee\u3011 <\/div>\n          <div class=\"blog-card-excerpt\">\u751f\u7406\u304c\u9045\u308c\u3066\u3044\u308b\u3001\u4f53\u8abf\u306b\u5909\u5316\u3092\u611f\u3058\u308b\u306a\u3069\u598a\u5a20\u3092\u4e88\u611f\u3057\u305f\u969b\u3001\u7523\u5a66\u4eba\u79d1\u3092\u53d7\u8a3a\u3059\u308b\u307e\u3048\u306b\u624b\u306b\u53d6\u308a\u305f\u3044\u306e\u304c\u598a\u5a20\u691c\u67fb\u85ac\u3067\u3059\u3002\u3053\u306e\u8a18\u4e8b\u3067\u306f\u598a\u5a20\u691c\u67fb\u85ac\u306e\u4ed5...<\/div>\n      <\/div>\n    <\/a>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"c5\"><span class=\"ez-toc-section\" id=\"How_to_distinguish_between_very_early_symptoms_and_menstruation\"><\/span>How to distinguish between very early symptoms and menstruation<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p>Among the symptoms that appear in the very first trimester of pregnancy, implantation bleeding is often thought by many to be a sign that the woman may have had her period.<\/p>\n\n\n\n<p>Implantation bleeding is a symptom that occurs in the third or fourth week of pregnancy, around the same time as the expected start of the period.<\/p>\n\n\n\n<p>The following points can help you distinguish between implantation bleeding in the first trimester of pregnancy and a menstrual period.

If your menstruation is a 28-day cycle, you are six weeks from the day your last menstruation started (week 6 of pregnancy).<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"c8-2\"><span class=\"ez-toc-section\" id=\"Submit_a_Pregnancy_Notification_Form_and_receive_a_Maternal_and_Child_Health_Handbook\"><\/span>Submit a Pregnancy Notification Form and receive a Maternal and Child Health Handbook<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p>The timing varies depending on the hospital you visit, but in many cases, a pregnancy notification form is issued when the baby&#8217;s heartbeat can be confirmed. When you submit the pregnancy notification form to the local authority, you will receive a Maternal and Child Health Handbook.<\/p>\n\n\n\n<p>The Maternal and Child Health Handbook is to be used for future antenatal check-ups and to record the progress of your pregnancy, so make sure you get it before your first antenatal check-up.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"c8-3\"><span class=\"ez-toc-section\" id=\"Consider_NIPT\"><\/span>Consider NIPT<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p>As soon as the pregnancy is confirmed by an ultrasound, a <a href=\"https:\/\/www.hiro-clinic.or.jp\/nipt\/nipt\/\">NIPT<\/a> can be performed, which estimates the amount of foetal DNA in the mother&#8217;s blood to determine if the foetus has <a href=\"https:\/\/www.hiro-clinic.or.jp\/nipt\/about-down-syndrome\/?lang=en\">Down syndrome (21 trisomy)<\/a>, <a href=\"https:\/\/www.hiro-clinic.or.jp\/nipt\/edwards-syndrome\/?lang=en\">Edwards syndrome (18 trisomy)<\/a>, <a href=\"https:\/\/www.hiro-clinic.or.jp\/nipt\/patau-syndrome\/?lang=en\">Patau syndrome<\/a> and other chromosomal abnormalities.<\/p>\n\n\n\n<p>Although it is a non-confirmatory test, it is more accurate than conventional prenatal diagnosis using maternal blood, with a sensitivity and specificity of 99.9%.

Be careful not to consume too much and limit yourself to one or two cups a day.<\/p>\n\n\n\n<p>If you are taking any medication for a pre-existing medical condition, see your doctor immediately to check if you can continue taking it during pregnancy.<\/p>\n\n\n\n<p>Also, try to avoid stress during pregnancy for the sake of your baby. You should not let your guard down too much, but you should not be too nervous and find time to relax and enjoy your pregnancy without putting too much strain on your mind and body.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"c9-2\"><span class=\"ez-toc-section\" id=\"Threatened_miscarriage\"><\/span>Threatened miscarriage<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p>A condition in which the foetus remains in the uterus and is one step away from miscarriage is called an imminent miscarriage.

If your period is late, or if you are feeling somewhat less well than usual, check with a pregnancy test.<\/p>\n\n\n\n<p>Finding out about the pregnancy at the right time allows for planned <a href=\"https:\/\/www.hiro-clinic.or.jp\/nipt\/nipt\/\">NIPT<\/a> and amniotic fluid tests to be carried out. A planned <a href=\"https:\/\/www.hiro-clinic.or.jp\/nipt\/nipt\/\">NIPT<\/a> or amnio test is easier on both the mother and the baby.<\/p>\n\n\n\n<p>If you are thinking of having a <a href=\"https:\/\/www.hiro-clinic.or.jp\/nipt\/\">NIPT<\/a> when you become pregnant, please consider visiting <a href=\"https:\/\/www.hiro-clinic.or.jp\/nipt\/nipt\/\">Hiro Clinic NIPT<\/a>, where the test can be performed as soon as the pregnancy is confirmed by an ultrasound scan.<br>Hiro Clinic can help you undergo testing with peace of mind, with up-to-date information and after-sales support based on clinical research.<br>(Hiro Clinic uses the data as clinical research data after obtaining the client&#8217;s consent.\uff09<\/p>\n\n\n\n    <a href=\"\/nipt\/nipt\/nipt\/\" class=\"blog-card\">\n      <div class=\"blog-card-content\">\n          <div class=\"blog-card-title\">NIPT\uff08\u65b0\u578b\u51fa\u751f\u524d\u8a3a\u65ad\uff09\u3067\u77e5\u7684\u969c\u5bb3\u304c\u308f\u304b\u308b <\/div>\n          <div class=\"blog-card-excerpt\">\u30d2\u30ed\u30af\u30ea\u30cb\u30c3\u30af\u3067\u884c\u3063\u3066\u3044\u308bNIPT\u306e\u307e\u3068\u3081\u3067\u3059\u3002\u30d2\u30ed\u30af\u30ea\u30cb\u30c3\u30af\u306eNIPT\u3067\u306f\u77e5\u7684\u969c\u5bb3\u30fb\u767a\u9054\u969c\u5bb3\u3092\u4f34\u3046\u591a\u6570\u306e\u75be\u60a3\u3092\u51fa\u751f\u524d\u306b\u691c\u51fa\u3059\u308b\u3053\u3068\u304c\u53ef\u80fd\u3067...<\/div>\n      <\/div>\n    <\/a>\n\n\n\n<div class=\"wp-block-group references\"><div class=\"wp-block-group__inner-container is-layout-flow wp-block-group-is-layout-flow\">\n<p>\u3010References\u3011<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Japan Society of Obstetrics and Gynaecology &#8211; <a href=\"https:\/\/www.jsog.or.jp\/modules\/diseases\/index.php?content_id=4#:~:text=%E5%88%87%E8%BF%AB%E6%B5%81%E7%94%A3%E3%81%A8%E3%81%AF%E3%81%AA%E3%82%93%E3%81%A7,%E3%81%AA%E3%81%84%E3%81%A8%E3%81%84%E3%82%8F%E3%82%8C%E3%81%A6%E3%81%84%E3%81%BE%E3%81%99%E3%80%82\">Miscarriage and imminent miscarriage<\/a><\/li>\n<\/ul>\n<\/div><\/div>\n","protected":false},"excerpt":{"rendered":"Summary of this arti&#8230;\n <a href=\"https:\/\/www.hiro-clinic.or.jp\/nipt\/fertilization-to-implantation\/?lang=en\">\u7d9a\u304d\u3092\u8aad\u3080<\/a>","protected":false},"author":13,"featured_media":25350,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"_acf_changed":false,"footnotes":""},"categories":[206],"tags":[],"class_list":["post-71429","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-pregnancy-questions"],"acf":[],"_links":{"self":[{"href":"https:\/\/www.hiro-clinic.or.jp\/nipt\/wp-json\/wp\/v2\/posts\/71429","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.hiro-clinic.or.jp\/nipt\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.hiro-clinic.or.jp\/nipt\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.hiro-clinic.or.jp\/nipt\/wp-json\/wp\/v2\/users\/13"}],"replies":[{"embeddable":true,"href":"https:\/\/www.hiro-clinic.or.jp\/nipt\/wp-json\/wp\/v2\/comments?post=71429"}],"version-history":[{"count":6,"href":"https:\/\/www.hiro-clinic.or.jp\/nipt\/wp-json\/wp\/v2\/posts\/71429\/revisions"}],"predecessor-version":[{"id":118107,"href":"https:\/\/www.hiro-clinic.or.jp\/nipt\/wp-json\/wp\/v2\/posts\/71429\/revisions\/118107"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.hiro-clinic.or.jp\/nipt\/wp-json\/wp\/v2\/media\/25350"}],"wp:attachment":[{"href":"https:\/\/www.hiro-clinic.or.jp\/nipt\/wp-json\/wp\/v2\/media?parent=71429"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.hiro-clinic.or.jp\/nipt\/wp-json\/wp\/v2\/categories?post=71429"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.hiro-clinic.or.jp\/nipt\/wp-json\/wp\/v2\/tags?post=71429"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
