Whether or not a pregnant woman who bleeds in the early stages of IVF pregnancy can keep her fetus varies from person to person, mainly due to factors such as the amount of bleeding, whether or not it is combined with abdominal pain and the development of the embryo. Vaginal bleeding in the early stages of pregnancy may be normal, usually the amount is not much, less than the amount of menstruation, coffee-colored or light red, and there is no abdominal pain or discomfort. If you go to the hospital to test progesterone, estradiol and blood human chorionic gonadotropin HCG, the values are normal, which means that the embryo is developing well. Pregnant women should take measures to keep warm, should not be overworked, prohibit sexual intercourse, keep bowel movement smooth, do not consume oily and cold food, maintain a relaxed mood, do not be too nervous, and pay attention to closely observe their own physical condition. Pregnant women who bleed more in the early stages of pregnancy, like menstruation, with bright red color and blood clots, accompanied by abdominal pain, swelling and discomfort, may be due to chromosomal abnormality or genetic abnormality of the embryo, hormonal secretion disorders in the mother’s body, congenital developmental abnormality of the uterus, immune system diseases, viral infections, overwork, excessive pressure, external impact, improper use of medication, bad habits, and other factors that lead to miscarriage. Bleeding can also be caused by ectopic pregnancy, cervical polyps, uterine pathology, gravida, etc. All of the above are very dangerous. If a pregnant woman is bleeding at the beginning of her IVF pregnancy, please go to a regular hospital immediately for examination and active treatment under the guidance of the doctor to avoid adverse consequences.
