class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p>At 14 weeks of pregnancy, the placenta is nearing completion and begins to prepare to receive nutrients from the umbilical cord. This is the time when the fetus&#8217;s organs, muscles, neck, limbs, and other parts of the body begin to develop. Although the subcutaneous tissue (fat) has not yet formed, the skin gradually thickens and downy hair begins to grow. The baby&#8217;s heart also begins to beat steadily, with a heart rate of approximately 150 beats per minute. This is more than double the mother&#8217;s heart rate (approximately 60 to 70 beats per minute).<\/p>\n\n\n\n<p>At 14 weeks pregnant, the baby&#8217;s size is approximately 90mm in crown-rump length (CRL) and weight is about 20-25g. An abdominal ultrasound scan may show the baby&#8217;s stomach bubble and urine accumulating in the bladder. At 14 weeks pregnant, the baby turns over in the amniotic fluid and begins to move its arms and legs actively. However, it is not until the 18th week of pregnancy that you can feel fetal movement.<\/p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-full\"><img decoding=\"async\" width=\"600\" height=\"370\" src=\"\/nipt\/wp-content\/uploads\/2021\/12\/0ac1ed4c442391e07ce3e424f88116eb.jpg\" alt=\"\u598a\u5a2014\u9031\u76ee\u30a8\u30b3\u30fc\u5199\u771f\" class=\"wp-image-20082\"\/><\/figure><\/div>\n\n<p>Ultrasound photo taken at 14 weeks of pregnancy.<\/p>\n\n\n<h3 class=\"wp-block-heading\" id=\"c1-2\"><span class=\"ez-toc-section\" id=\"Determining_the_babys_gender_by_ultrasound\"><\/span><strong>Determining the baby&#8217;s gender by ultrasound<\/strong><span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p>Sex differentiation of a fetus occurs at the time of fertilization. The chromosomes that determine gender (sex chromosomes) are the &#8220;X chromosome&#8221; and the &#8220;Y chromosome,&#8221; so if a man is XY, then he will have XX chromosomes, and if a woman is XX chromosomes. If an abnormality occurs in the sex chromosomes, it will result in aneuploidy, such as one X or XXY, which often leads to congenital disorders.<\/p>\n\n\n\n<p>By the time you reach 14 weeks of pregnancy, your baby&#8217;s external genitalia is almost fully formed. However, it is generally not until the 18th week of pregnancy that you can determine your baby&#8217;s gender with an ultrasound, and even then, it can be difficult to determine the gender with certainty due to factors such as the position of your baby&#8217;s body.<\/p>\n\n\n\n<p>Depending on the medical institution, the gender determined by the ultrasound examination during the prenatal checkup may not be communicated to the pregnant woman. If you are a pregnant woman who wants to know the gender of the baby before giving birth, check in advance whether you can be told the gender at the ultrasound examination.<\/p>\n\n\n\n    <a href=\"\/nipt\/xlinked-recessive-inheritance\/\" class=\"blog-card\">\n      <div class=\"blog-card-content\">\n          <div class=\"blog-card-title\">\u4f34\u6027\u6f5c\u6027\u907a\u4f1d~\u8d64\u3061\u3083\u3093\u306e\u6027\u5225\u691c\u67fb\uff5cNIPT\uff08\u65b0\u578b\u51fa\u751f\u524d\u691c\u67fb\uff09\u3010\u533b\u5e2b\u76e3\u4fee\u3011 <\/div>\n          <div class=\"blog-card-excerpt\">\u306a\u305c\u3001\u8d64\u3061\u3083\u3093\u306e\u6027\u5225\u3092\u751f\u307e\u308c\u308b\u524d\u306b\u77e5\u308b\u5fc5\u8981\u304c\u3042\u308b\u306e\u3067\u3057\u3087\u3046\u304b\uff1f\u305d\u306e\u7406\u7531\u3092X-linked recessive inheritance\uff08\u4f34\u6027\u6f5c...<\/div>\n      <\/div>\n    <\/a>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"c2\"><span class=\"ez-toc-section\" id=\"14_weeks_pregnant_woman\"><\/span><strong>14 weeks pregnant woman<\/strong><span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"c2-1\"><span class=\"ez-toc-section\" id=\"Maternal_condition_at_14_weeks_of_pregnancy\"><\/span>Maternal condition at 14 weeks of pregnancy<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p>At 14 weeks of pregnancy, the placenta is nearing completion and morning sickness will subside. This is generally considered to be the time when you are approaching the &#8220;stable period&#8221; when the risk of miscarriage is low.<\/p>\n\n\n\n<p>During the 14th week of pregnancy, your physical condition will be more stable than during the early stages of pregnancy, so it is important to have a balanced diet and exercise moderately. However, as the baby grows and the uterus gets larger, many pregnant women suffer from frequent urination and urinary incontinence, and refrain from exercising or going out.<\/p>\n\n\n\n<p>During the 14th week of pregnancy, once the peak of morning sickness has passed, it&#8217;s a good idea to take a walk around the neighborhood or do some light stretching indoors to change your mood and improve blood circulation.<\/p>\n\n\n\n<p>In addition, since developing pregnancy gingivitis can lead to premature birth, it is also important to have a dental checkup at a dental clinic.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"c2-2\"><span class=\"ez-toc-section\" id=\"Common_problems_that_can_occur_during_the_14th_week_of_pregnancy_and_things_to_be_aware_of\"><\/span>Common problems that can occur during the 14th week of pregnancy and things to be aware of<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<h4 class=\"wp-block-heading\" id=\"c2-2-1\">Beware of iron deficiency anemia<\/h4>\n\n\n\n<p>One of the problems that can easily occur during pregnancy is iron deficiency anemia. Even before pregnancy, one in five modern women suffer from iron deficiency anemia, and they tend to be chronically deficient in iron. In addition, twice as much iron is needed to produce red blood cells for the baby, and it is said that about 95% of anemia during pregnancy is due to iron deficiency.<\/p>\n\n\n\n<p>Iron deficiency anemia occurs when the body is unable to produce hemoglobin, which is contained in red blood cells, due to a lack of iron in the body. Hemoglobin plays a role in transporting oxygen in the body, and iron deficiency often causes shortness of breath, palpitations, headaches, dizziness, and fatigue when exercising.<\/p>\n\n\n\n<h5 class=\"wp-block-heading\" id=\"c2-2-1-1\"><strong>Effects of iron deficiency anemia on the fetus<\/strong><\/h5>\n\n\n\n<p>Iron deficiency anemia in pregnant women impairs the normal growth and development of the fetus. In particular, a sufficient supply of oxygen is necessary for brain development. To prevent oxygen deficiency in the baby, be sure to eat a well-balanced diet and take in an appropriate amount of iron.<\/p>\n\n\n\n<p>Anemia in pregnant women can also be caused by a lack of folic acid, not just iron. Folic acid deficiency anemia can cause congenital abnormalities in the fetus&#8217;s brain and spinal cord, so care must be taken.<\/p>\n\n\n\n<p>Both iron deficiency anemia and folic acid deficiency anemia can be diagnosed through a blood test during a prenatal checkup. Follow your doctor&#8217;s instructions and take iron supplements and folic acid supplements.<\/p>\n\n\n\n    <a href=\"\/nipt\/folic-acid\/\" class=\"blog-card\">\n      <div class=\"blog-card-content\">\n          <div class=\"blog-card-title\">\u598a\u5a20\u4e2d\u306e\u8449\u9178\u6442\u53d6\u306f\u3044\u3064\u304b\u3089\u3044\u3064\u307e\u3067\uff1f\u3010\u533b\u5e2b\u76e3\u4fee\u3011 <\/div>\n          <div class=\"blog-card-excerpt\">\u598a\u5a20\u524d\u304b\u3089\u598a\u5a20\u5f8c\u671f\u307e\u3067\u6442\u53d6\u304c\u671b\u307e\u3057\u3044\u3068\u3055\u308c\u308b\u8449\u9178\u3002\u3053\u306e\u8a18\u4e8b\u3067\u306f\u8449\u9178\u306e\u6210\u5206\u304c\u3082\u305f\u3089\u3059\u52b9\u679c\u3068\u63a8\u5968\u91cf\u3001\u598a\u5a20\u306b\u8449\u9178\u304c\u306a\u305c\u5fc5\u8981\u3068\u3055\u308c\u308b\u306e\u304b\u3001\u6bcd\u4f53\u3068\u8d64\u3061...<\/div>\n      <\/div>\n    <\/a>\n\n\n\n<h4 class=\"wp-block-heading\" id=\"c2-2-2\"><strong>Risk of pregnancy-induced hypertension and gestational diabetes<\/strong><\/h4>\n\n\n\n<p>In the early stages of pregnancy, many pregnant women lose their appetite due to morning sickness, while others eat too many calories due to morning sickness. Also, at the 14th week of pregnancy, when morning sickness subsides, many women find that their appetite continues and they end up gaining weight.<\/p>\n\n\n\n<p>Rapid weight gain during pregnancy is said to increase the risk of pregnancy-induced hypertension and gestational diabetes. Pregnancy-induced hypertension reduces blood flow, resulting in insufficient nutrition and oxygen reaching the fetus, leading to growth retardation. Caution is required as this increases the risk of low birth weight babies weighing less than 2500g, premature birth, and stillbirth. Gestational diabetes also supplies the fetus with excess sugar, which can lead to organ enlargement and large babies weighing over 4000g.<\/p>\n\n\n\n<p>The 14th week of pregnancy is when morning sickness subsides and appetite returns. However, for the sake of your baby&#8217;s health, you should still try to eat an appropriate amount of nutritious, balanced food.<\/p>\n\n\n\n<h4 class=\"wp-block-heading\" id=\"c2-2-3\"><strong>Risk of miscarriage at 14 weeks pregnant<\/strong><\/h4>\n\n\n\n<p>At 14 weeks of pregnancy, the placenta stabilizes and the risk of miscarriage decreases. Morning sickness subsides, so many pregnant women resume work and exercise that they had refrained from during the early stages of pregnancy.<\/p>\n\n\n\n<p>Miscarriages in the early stages of pregnancy are often caused by chromosomal abnormalities in the fetus. On the other hand, miscarriages after the 12th week of pregnancy are said to be caused by the mother&#8217;s body as well.
