How old is the baby? Gestational sac size on day 50 of pregnancy

First, the 50th day of pregnancy is about the transitional period from the 7th week to the 8th week of pregnancy. In the 7th week, the fetus grows to 1.33cm, the embryo has human embryonic form, the somites have all differentiated, the limbs have separated, and each system has further developed. B-ultrasound clearly showed the fetal bud and fetal heartbeat, the fetal sac accounted for about 1 / 3 of the uterine cavity; and in the eighth week, the fetus grew to 1.66 cm, the fetal shape has been determined, can be divided into fetal head, body and limbs, the fetal head is larger than the trunk. B ultrasound showed that the fetal sac accounted for about 1 / 2 of the official cavity, the fetal morphology and movement were clearly visible, and the yolk sac could be seen.

Second, due to emotional stress and other reasons, pregnant women have delayed menstruation, ovulation and late conception, resulting in a smaller gestational sac than the actual number of days of menopause. For example, 50 days of menopause, but the examination found that the gestational sac is only 40 days, which is a normal situation. As long as the dynamic examination of one week shows that the value of chorionic gonadotropin and progesterone is gradually increasing, the gestational sac continues to grow, and the embryo bud and fetal heart gradually appear, which means that the gestational sac is small due to physiological reasons such as the wrong ovulation period and late pregnancy time, which can be continued Follow up pregnancy.

Third, due to the poor development of sperm and eggs, pregnant women infected with mycoplasma, chlamydia, rubella virus during pregnancy or pregnant women exposed to toxic and harmful substances during pregnancy and other reasons, resulting in poor gestational sac development, less than normal months. With the passage of time, the gestational sac will continue to grow, but there is no fetal bud and fetal heart rate. In this case, the gestational sac is not healthy and will eventually lead to abortion.
