Some pregnant women can be tested through abdominal B-ultrasound at 5 weeks of pregnancy, but some pregnant women cannot find the fetal heart rate or even the embryo bud. In order to reduce the re-examination rate of postgraduate entrance examinations, we should choose a golden period. The time when the embryo bud and fetal heart rate appear is between 40 and 60 days of pregnancy. Of course, the time of onset is different for every pregnant woman, and it can occur in the morning, afternoon, and evening. We should check at 7 weeks of pregnancy, so we can basically check once. Obstetric B-ultrasound has different costs due to different projects and different instruments used. And it varies depending on the city, hospital level, etc. Taking Shanghai as an example, if you are a Shanghai resident and have medical insurance, the most common two-dimensional black and white B-ultrasound costs 30 yuan. If you do a 3D, 4D or color B-ultrasound, or an ultrasound that involves checking the 11 organs of the fetus like a major fetal malformation screening during pregnancy, the cost will of course be different. The price of a 3D B-ultrasound in the obstetrics department of a tertiary hospital is generally between 300 and 400 yuan. In addition, the cost of ultrasound for single and twin babies is also different. In the early stages of pregnancy, every pregnant woman needs to check the fetal heart rate. The traditional examination method is abdominal B-ultrasound examination. However, the first ultrasound scan during pregnancy leaves a bad impression on many pregnant women. During pregnancy, many pregnant women undergo reexamination because they cannot see the test tube embryo bud and fetal heart rate. Therefore, it is necessary to choose the right time in the early stages of pregnancy, otherwise it may result in repeated pregnancy tests. If the examination is done during early pregnancy, the pregnant woman may be required to undergo a transvaginal ultrasound, especially obese pregnant women must pay attention. Abdominal B-ultrasound does not show clear information about the test tube embryo that has just formed the embryonic bud, fetal heart rate and fetal heartbeat, and there may be certain blind spots. Therefore, transvaginal ultrasound may be necessary in the morning, especially for obese pregnant women. The abdomen of obese pregnant women will also be thickened, so ultrasound cannot detect it. Vaginal ultrasound is an endoscopic examination that can perfectly avoid abdominal fat, check the pregnancy environment in the uterus, and detect it more clearly. In order to check the fetal heart rate and fetal heart rate, many pregnant women have paid attention to it. During early pregnancy, you must improve your physical fitness, increase nutrition, arrange your time reasonably, and exercise more, so as to improve your physical fitness. Pregnant women with high physical fitness can promote the rapid growth, development and improvement of test tube embryos. Pregnant mothers cannot ignore this. Early pregnancy is important for the complete development of the embryo. The growth and development of test tube embryos also affects the appearance of test tube embryo buds and fetal heartbeat. There is no need to ignore it. |
