At the beginning of pregnancy, the pregnant woman is in the gestational sac, not in the uterus. Of course, as time goes by, the embryo will gradually develop and the gestational sac will become larger. Normally, a embryo will form, but some pregnant women are different from others. Their gestational sac is getting bigger, but there is no embryo. So why is there no embryo when the gestational sac gets bigger?
1. Ultrasound examination too early
In early pregnancy, the formation time of gestational sac, fetal bud, and fetal heart is different. The gestational sac forms between 30-40 days of pregnancy, the fetal bud forms between 40-50 days of pregnancy, and the formation time of the fetal heart is between 50-60 days of pregnancy. When the expectant mother undergoes ultrasound examination too early, that is, before the formation of the gestational sac and gestational sac, only the gestational sac can be seen without the gestational sac and fetal heart. In this case, expectant mothers should wait for 2-3 weeks before going for an ultrasound examination to see if they can see fetal sprouts and heart rate.
2. Late conception time
The menstrual cycle and ovulation period of expectant mothers are different. Some expectant mothers ovulate later, so their conception time is later than that of ordinary people. This can result in the same gestational age when they go for examination, but some have large gestational sacs and fetal buds, while others only see the gestational sac but not the fetal buds. This is a relatively normal situation in early pregnancy, expectant mothers can wait 1-2 weeks before going for the examination. However, there is a prerequisite, which is to first check whether the growth of HCG and progesterone is normal.
3. Embryo stops developing
During the B-ultrasound examination, if the gestational sac is long but there is no fetal bud or heart, it may indicate that the embryo has stopped developing. This is related to early pregnancy infections such as mycoplasma, chlamydia, rubella virus, or exposure to harmful and toxic substances. If this situation is not detected through ultrasound examination, it will eventually result in a natural miscarriage. However, it is still recommended that pregnant women terminate their pregnancy through induced abortion, as the earlier the abortion, the less impact it will have on the pregnant woman.
4. Poor sperm quality
Poor sperm quality, self defects, or the cessation of development due to adverse factors during the development process may also result in only seeing the gestational sac growing but no fetal bud or heart rate. In this situation, it is recommended that expectant mothers go to a regular hospital for curettage surgery. After resting well, it is best for both husband and wife to go to the hospital for examinations on the four aspects of eugenics, anti sperm antibodies, anti cardiolipin antibodies, anti chorionic gonadotropin antibodies, sperm quality, egg development, etc. After identifying the specific cause, targeted treatment should be given, and pregnancy should be carried out one year later.
The above is the encyclopedia introduction about why there is no fetal bud due to the enlargement of the gestational sac. In general, in most cases, only the gestational sac is seen to be long but there is no fetal bud or heart rate due to premature examination. It is recommended that expectant mothers in early pregnancy go to the hospital for B-ultrasound examination later. This not only avoids affecting the pregnant woman's mood due to the inability to see the fetal bud or heart rate, but also avoids wasting the time and money of the pregnant woman's re examination.
