What is the reason for the gestational sac to grow but no fetal bud or fetal heart?

Pregnant women should go to the hospital for regular check-ups. Today's medical technology is relatively advanced. If some problems arise, conclusions can generally be drawn through examination. For example, during the examination, if the pregnant woman is found to have a gestational sac but no fetal bud or fetal heartbeat, there are many reasons for this symptom. For example, the B-ultrasound examination may be performed too early and the fetal bud and fetal heartbeat have not yet formed. If the conception occurs late, or the embryo stops developing, this phenomenon may occur.

1. Ultrasound examination too early

In the early pregnancy stage, the formation time of the gestational sac, fetal bud and fetal heart is different. The gestational sac is formed at 30-40 days of pregnancy, the fetal bud is formed at 40-50 days of pregnancy, and the fetal heart is formed at 50-60 days of pregnancy. When the expectant mother has an ultrasound examination too early, that is, when the embryo bud and fetal bud have not yet formed, of course only the gestational sac can be seen but no embryo bud or fetal heartbeat.

what to do:

In this case, the expectant mother should wait 2-3 weeks before going for another ultrasound to see if the embryo and fetal heartbeat can be seen.

2. Late conception

The menstrual cycle and ovulation period of expectant mothers are different. Some expectant mothers ovulate later, so the time of conception is also later than ordinary people. When they go for a check-up, they will show the same gestational age, but some have a large gestational sac and fetal buds and fetal heartbeats, while others only show the gestational sac but no fetal buds and fetal heartbeats.

what to do:

This is a relatively normal situation in early pregnancy. Expectant mothers can wait 1-2 weeks before going for a check-up. However, there is a prerequisite, which is to first check whether the growth of HCG and progesterone is normal.

3. The embryo stops developing

During the B-ultrasound examination, if the gestational sac is growing but there is no fetal bud or fetal heart, it may be that the embryo has stopped developing. This is related to infection with mycoplasma, chlamydia, rubella virus or contact with harmful and toxic substances in early pregnancy.

what to do:

In this case, if it is not discovered through B-ultrasound examination, it will eventually lead to spontaneous abortion. However, it is still recommended that pregnant women terminate their pregnancy through artificial abortion, because the earlier the abortion, the less impact it will have on the pregnant woman.

4. Poor sperm quality

If the sperm quality is poor, the sperm itself has defects, or the development is stopped due to adverse factors during the development process, the gestational sac may be seen growing but no embryonic bud or fetal heart.

what to do:

In this case, it is recommended that the expectant mother go to a regular hospital for a uterine curettage. After a good rest, it is best for both husband and wife to go to the hospital for examinations of four eugenics items, antisperm antibodies, antiphospholipid antibodies, anti-chorionic gonadotropin antibodies, sperm quality, egg development, etc. After finding out the specific cause of the disease, symptomatic treatment should be given and they can try to get pregnant again after one year.

5. Health Tips

In most cases, only seeing the gestational sac growing but no fetal bud or fetal heartbeat is because the examination is done too early. It is recommended that expectant mothers in the early stages of pregnancy go to the hospital for an ultrasound examination later. This will not only not affect the mood of the pregnant woman due to the inability to see the fetal bud or fetal heartbeat, but also will not waste the pregnant woman's time and money for another follow-up examination.
