If you have slight bleeding in the first month of pregnancy, the first thing to consider is that preterm miscarriage is more likely. In this case, you should go to the hospital to check the gynecological ultrasound to see the development of the embryo. If the ultrasound reveals the echo of the gestational sac in the uterine cavity and the fetal heartbeat is good, if you intend to have a baby, you should be given medication to keep the pregnancy alive. The common medication used to keep the pregnancy alive is progesterone capsules, dextran tablets or progesterone injection, which are all effective. During the process of fetal preservation, you should pay attention to rest, avoid overexertion, pay attention to the prohibition of sexual intercourse, and go to the hospital promptly if there is an increase in vaginal bleeding. If there is no abnormality, regular prenatal checkups will be fine. If you do not see the echo of the gestational sac in the uterine cavity by ultrasound, you should be alert to the occurrence of ectopic pregnancy.
