Is it normal to not see the gestational sac at 6 weeks of pregnancy?

In the early stages of pregnancy, B-ultrasound can reveal that there is a cowpea-sized object attached to the inner wall of the uterus, which is the gestational sac. Then the gestational sac will begin to divide at an alarming rate and will form a human shape in a very short time. This means that seeing the gestational sac in the uterus is a real pregnancy. So, is it normal not to see the gestational sac at 6 weeks of pregnancy? The editor will take a look at it with everyone below.

Is it normal to not see the fetal sac at 6 weeks of pregnancy?

1. If you cannot see the gestational sac during B-ultrasound during pregnancy, it is abnormal, unless you have any uncomfortable symptoms. It is recommended to check the uterine cavity again in the next few days to see the fetal sac to confirm that it is an intrauterine pregnancy. If the fetal sac is still not seen and the blood test data continues to increase, it is likely that there is an ectopic pregnancy.

2. You are only six weeks pregnant now, and the pregnancy period is very short, so the gestational sac cannot be seen by B-ultrasound. Judging from the progesterone level and hcg, it is better to double them. This is a normal situation. It is recommended to go for B-ultrasound after ten days, and the gestational sac should be visible.

Reasons for a small gestational sac at 6 weeks of pregnancy

1. Physiological reasons

Women's anxiety and other reasons can cause delayed menstruation, delayed ovulation, and late pregnancy, which can lead to the fetal sac being smaller than the actual number of days of amenorrhea. This kind of small size is normal. As long as the test after one week shows that the HCG value and progesterone value are gradually increasing, the gestational sac is continuing to grow, and the fetal bud, fetal heart rate and fetal heartbeat are gradually appearing, then it is ok.

2. Incomplete development of the fetal sac

Incomplete development of male sperm or egg cells; infection of chlamydia, mycoplasma, or rubella virus in pregnant women; exposure to harmful substances during pregnancy; these conditions may cause incomplete and small fetal sac. In this case, the gestational sac will continue to grow during the pregnancy, but the embryo, fetal heartbeat and fetal bud will not be seen, eventually causing miscarriage in pregnant women.

Generally speaking, it is abnormal not to see the fetal sac at 6 weeks of pregnancy. Once this happens, further examination should be done immediately to determine the cause. The fetus in the early stages of pregnancy is very likely to suffer some unimaginable adverse effects due to some unfavorable factors. Therefore, you must be cautious in the early examinations and avoid regretting it for the rest of your life due to momentary negligence.
