In a normal pregnancy there is no bleeding. Once vaginal bleeding occurs, we should be alert to the possibility of preterm miscarriage or embryonic arrest. The first thing to do is to go to the hospital for an ultrasound to check the development of the gestational sac in the uterine cavity. If the development of the gestational sac is normal, hospitalization should be arranged in time. If the gestational sac is already suggesting that the embryo has stopped developing, the next step is to perform a timely operation to remove the uterus. If nothing is seen in the uterine cavity, blood will be drawn for two blood values, human chorionic gonadotropin and progesterone, which will be repeated 2-3 days later to see how the blood values have increased. If the blood levels increase very slowly or drop, it is possible that the embryo has stopped developing or has spontaneously aborted. In rare cases, the bleeding may be caused by a cervical polyp, the most common being a cervical polyp. If the cervical polyp causes bleeding for a long time, it can be removed.
