How long does it take to see the embryo during pregnancy?

After a woman becomes pregnant, she must do a pregnancy check-up on time. Because prenatal examinations are of great practical significance, we can immediately know the growth and development status of the fetus, and if any abnormalities are found, they can be properly handled. The fetus must have a fetal bud and fetal heartbeat, but some pregnant women go for a prenatal check-up and find that there is no fetal bud and fetal heartbeat for a long time or the fetal development is incomplete. So, how long is the latest time for a fetal bud to appear during pregnancy?

1. How long is the latest time of pregnancy before the embryo bud can be seen

1. Under normal circumstances, the initial fetal heartbeat can be seen at six weeks, and at the latest at eight weeks. Expectant mothers usually see the gestational sac at 5 weeks of pregnancy, and the fetal bud, fetal heart and initial primitive heart tube pulsation at 6-7 weeks of pregnancy. Seeing a fetal heartbeat is diagnostic in early pregnancy and suggests a live fetus. If the embryo, fetal heart and fetal heartbeat are not seen after 7 weeks of pregnancy. It is necessary to determine whether the pregnancy week is consistent with the menstrual period week, dynamically check the blood HCG and progesterone levels, and review the B-ultrasound status to judge whether the embryonic development is good based on the results.

2. Generally speaking, the embryonic bud and fetal heart rate are important indicators of the healthy growth of a child. However, in many cases, the baby will stop growing and developing due to various reasons, and the embryonic bud and fetal heart rate will not appear. There are two main manifestations of test tube embryo termination of development. The first is continuous vaginal bleeding. The second is that although there is no symptom of vaginal bleeding, the ultrasound reveals that the test tube embryo has terminated development and there is no embryo, fetal heart rate or fetal heartbeat.

2. Reasons why the fetal heart rate seems slow

1. The fetal bud and fetal heart rate seem slow, which may be caused by irregular menstruation and slow ovulation in women. Due to slow ovulation, embryo implantation is relatively late. Although the fetal bud and fetal heart rate should be seen according to the date calculation, the actual sperm-egg combination is delayed, so the fetal bud and fetal heart rate seem slow.

2. Generally, the fetal bud and fetal heart rate can be detected through B-ultrasound at about 6 weeks of pregnancy. If they are not yet detected, pregnant women do not need to be too nervous and can wait for 2 weeks before checking again. However, if there is no embryonic bud or fetal heartbeat after more than 8 weeks, it may be that the fetus has stopped growing and developing, which requires attention.

3. If a pregnant woman is found to have no embryonic bud or fetal heartbeat before 6 weeks, but the test tube embryo is growing and developing normally, then it is okay, because the time of embryo implantation is different for each person, and the pregnancy conditions are also different. It is normal for the embryonic bud and fetal heartbeat to appear slow. Just follow the doctor's instructions and do a good job of follow-up visits.
