There are two possibilities for the gestational sac to deviate from the right corner of uterus. If it grows into the uterine cavity in the future, there should be no problem. However, if it grows to the uterine horn, it may lead to the possibility of cornual pregnancy and uterine rupture. If you have abdominal pain, you should pay attention.
Generally, after 50 days of menopause, I went to the hospital for the first B-ultrasound examination. If the menstruation is normal, I can see the gestational sac, primitive heart tube pulsation and embryo bud. Your situation suggests that I go to the hospital for a review in a week. If it still doesn't work, I think it's fetal arrest. In this case, I need to terminate the pregnancy.
If the gestational sac is more than 6 weeks pregnant and there is no embryo and fetal heart beating, we should consider the possibility of missed abortion, that is, embryo abortion. It is suggested that progesterone be injected to protect the fetus, and B-ultrasound should be reviewed one week later. If there is still no obvious pathogen, it can be diagnosed as missed abortion and abortion should be performed.
For normal intrauterine pregnancy, generally after 42 days after menopause, B-ultrasound can clearly see the embryo buds in the uterus and the heartbeat of the fetal heart tube. Some women with irregular menstrual cycle, or late ovulation and late implantation of fertilized eggs have embryo buds in their uterus, and the beating time of fetal heart tube will be relatively delayed, but it will not exceed 49 days after menopause and 56 days at the latest. If there is no intrauterine bud or fetal heart tube pulsation for more than 56 days, it should be diagnosed as fetal arrest. I suggest you go to the hospital for examination in time and follow the doctor's advice.
If there are bleeding symptoms, it is not excluded that it is caused by threatened abortion or missed abortion. This depends on whether the egg quality is mature, whether the sperm quality is high, and whether it is accompanied by gynecological inflammation, which will affect embryo development. So I suggest you go to the hospital for a check-up to avoid habitual abortion.
At the 50 th day of pregnancy, the gestational sac is the original placental tissue, which is a small embryo wrapped by amniotic membrane and vascular network. Gestational sac is the initial form of pregnancy. At that time, before the fetus was formed, the fetal heart beat when the embryo bud appeared. Gestational sac is also the product of ectopic pregnancy. Due to inflammation and adhesion, the fertilized egg did not enter the uterus on the 7th day. Usually ectopic pregnancy will bleed heavily, and generally speaking, the fetus can't survive. It can be seen that the size of gestational sac is related to the growth of fetus. So, what is the gestational sac size at 50 days of pregnancy? Pregnant for 50 days, in the transition stage from the seventh week to the eighth week. At the seventh week, the fetus grows to 1.33 cm, and the embryo has the shape of a human embryo. All parts of the body have been differentiated, the limbs are separated, and the system is further developed. B-ultrasound can clearly see the embryo bud and fetal heartbeat, and the fetal sac accounts for about1/3 of the uterine cavity; At the eighth week, the fetus grew to 1.66 cm, and its shape was fixed, which could be divided into fetal head, fetal body and fetal limb. The head of the fetus is bigger than the trunk. B-ultrasound showed that the fetal sac occupied about 1/2 of the official cavity, the fetal shape and fetal movement were clearly visible, and the yolk sac was visible.
4 weeks: the fetus is only 0.2 cm. As soon as the fertilized egg is implanted, the amniotic cavity is formed, and the volume is very small. Ultrasound shows no signs of pregnancy.
5 weeks: The fetus grows to 0.4 cm, enters the embryonic stage, the amniotic cavity expands, the primitive cardiovascular system appears, and there may be pulsation. B-ultrasound showed a small fetal sac, accounting for less than 1/4 of the uterine cavity, or a germ could be seen.
6 weeks: the fetus grows to 0.85 cm, and the fetal head, brain vesicles, frontal organs, respiratory organs, digestive organs, nerves and other organs differentiate. B-ultrasound can clearly see the fetal sac, and can see the embryo and fetal heartbeat.
Week 7: The fetus grows to 1.33 cm, and the embryo has the shape of human embryo, with differentiation of each segment, separation of limbs and further development of each system. B-ultrasound clearly showed the embryo bud and the fetal heartbeat, and the fetal sac occupied about 1/3 of the uterine cavity.
8 weeks: the fetus grows to 1.66 cm, and the fetal shape has been determined, which can be divided into fetal head, fetal body and fetal limb, and the fetal head is larger than the trunk. B-ultrasound showed that the fetal sac occupied about 1/2 of the official cavity, the fetal shape and fetal movement were clearly visible, and the yolk sac was visible.
9 weeks: The fetus grows to 2. 15 cm, the fetal head is larger than the carcass, and the performance of each part is clearer. The skull begins to calcify and the placenta begins to develop. B-ultrasound showed that the fetal sac almost filled the uterine cavity, the fetal contour was clearer and the placenta began to appear.
10 week: the fetus grows to 2.83 cm, all the organs of the fetus have been formed, and the placenta of the embryo has been formed. B-ultrasound showed that the fetal sac began to disappear, the crescent placenta was visible, and the fetus was moving in amniotic fluid.
