There is uncertainty as to whether bleeding on the 35th day of pregnancy can be kept. At present, the number of days of menopause is relatively short, the uterine cavity is not yet visible inside the obvious gestational sacs, can not be diagnosed as early intrauterine pregnancy or ectopic pregnancy, need to be based on the current blood HCG test out of the value of the general judgment. If the blood HCG value doubles well, the value of progesterone is also within the normal range, the bleeding is not very much, there is still hope for preservation. If the blood HCG value does not double well, and the bleeding is heavy, and the progesterone value is relatively low, the hope of keeping the pregnancy alive is not very high, and the possibility of ectopic pregnancy should also be taken into consideration. At present, during the bleeding period, you need to pay more attention to rest, prohibit sexual life, need to check the blood HCG value every other day, and later combined with the ultrasound examination, comprehensive analysis, clear diagnosis.
