What symptom does gestational sac have bad

summary

Gestational sac is the primordial placental tissue, which is wrapped by amniotic membrane and vascular network. Gestational sac is the initial form of pregnancy. At that time, the fetus was not formed, and the fetal heart beat when the embryo bud appeared. Gestational sac is also a product of ectopic pregnancy. The fertilized egg does not enter the uterus due to inflammation, adhesion and other factors on the 7th day. Usually, ectopic pregnancy will have massive bleeding, and generally speaking, the fetus cannot survive. The mother of little BB is an intrauterine pregnancy, but due to uterine dysplasia, the gestational sac breaks from the top of the uterus and enters the abdominal cavity. The villi around the gestational sac seek nutrients everywhere in the abdominal cavity, and then supply the fetus through the placenta. Usually such a fetus without the protection of the uterine environment, living environment is very bad, nutrition is also relatively poor, normal two months the fetus will die. Next, let's talk about the symptoms of this disease. I hope you can prevent it early.

What symptom does gestational sac have bad

First, 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 about 40 days in size. This kind of small gestational sac is normal. 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 fetal bud and fetal heart gradually appear, it means that the small gestational sac is caused by physiological reasons such as the wrong ovulation period and late pregnancy time, so pregnancy can continue.

Second: due to 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 development of gestational sac, 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.

Third: gestational sac is only seen in early pregnancy. Menstruation 28 ~ 30 days rule of women, 35 days after menopause, B ultrasound can see the gestational sac in the uterine cavity. The gestational sac is about 2 cm in diameter at 6 weeks and 5 cm at 10 weeks. The position of gestational sac in the fundus, anterior wall, posterior wall, upper part and middle part of the uterus is normal; the shape of round, oval and clear is normal; if the gestational sac is irregular, fuzzy and located in the lower part, and the pregnant woman has abdominal pain or vaginal bleeding at the same time, abortion may be necessary. Gestational sac is the primordial placental tissue, which is wrapped by amniotic membrane and vascular network. Gestational sac is the initial form of pregnancy. At that time, the fetus was not formed, and the fetal heart beat when the embryo bud appeared. In the second week of embryo implantation into endometrium, there is a large cavity called primary yolk sac on the ventral side of the embryo disc when the embryo develops to the second germ layer. The yolk sac shrinks and degenerates continuously during embryo development. However, the ectoderm on the wall of yolk sac is the earliest birthplace of blood cells, blood vessels and primordial germ cells - gestational sac, where the fetus will grow in the future.

matters needing attention

Empty gestational sac means that the embryo does not develop well. There are many reasons, such as poor sperm quality, environmental factors and so on, which will affect the embryo development. Sometimes, empty gestational sac will appear when the fertilized egg is late.
