40 days of pregnancy B-ultrasound gestational sac size to determine the gender

The current policy of having a second child policy has made people pay more attention to the issue of gender, because everyone wants a son and a daughter. It is every woman's dream to create a son and a daughter with their loved ones. When they are older, they will have children to take care of them. The warmth of a daughter is also a plus. So, can the ultrasound of the gestational sac at 40 days of pregnancy tell the boy or girl? Today, let’s learn whether it is really possible to tell the gender of the baby by measuring the 40-day gestational sac.

40-day fetal sac test for gender

Generally speaking, a small gestational sac may be due to anxiety, which may cause delayed menstruation, delayed ovulation, and late pregnancy, resulting in a gestational sac that is smaller than the actual number of days of amenorrhea. For example, the menstruation has not stopped for 50 days, but during examination it is found that the gestational sac is only about 40-day size. This kind of small gestational sac is normal. As long as a dynamic examination after one week shows that the levels of chorionic gonadotropin and progesterone are gradually increasing, the gestational sac continues to grow, and the embryo, fetal heartbeat and fetal heartbeat gradually appear, it means that the small gestational sac is caused by physiological reasons and pregnancy can continue. Therefore, the gestational sac cannot tell whether it is a boy or a girl. If the gestational sac is small, pregnant mothers should pay more attention to it, as it may not be a sign of having a boy or a girl, but a sign that the baby is not fully developed.

How long does it take for ultrasound to show the gestational sac?

The fetal sac is very small at first, and then gradually grows bigger. Under normal circumstances, after 5 weeks of pregnancy, a small gestational sac can be seen on B-ultrasound, which occupies less than 1/4 of the uterine cavity, or the embryonic bud and fetal heartbeat can be seen from it. If it is a normal intrauterine pregnancy, the gestational sac can be seen in the uterus through B-ultrasound around 40 days of pregnancy. However, due to individual differences and the early or late pregnancy time, some pregnant women may not be able to see it until around 45 days.

The above is the relevant information obtained by the editor based on the 40-day gestational sac test for gender. This kind of material can help everyone understand this issue very well, but in this universal two-child policy, we still have to choose the second child objectively, right? We can't let the eldest brother be more than ten years older than the second child, otherwise many problems will arise immediately. We still have to be objective.
