Vaginal bleeding occurs in the vast majority of women one or two weeks after the embryo has stopped developing. However, this time does not represent all women, and there is no uniform time frame depending on individual circumstances, so the clinical condition should prevail. When the embryo stops developing, the estrogen and progesterone in the body drop and the smooth muscles of the uterus contract, causing vaginal bleeding as a result of the detachment of the gestational sac from the uterine wall. However, some women do not have vaginal bleeding until after the abortion, and some women start bleeding before the embryo stops developing. The bleeding in the case of embryonic arrest is not particularly heavy, but rather you will see a brown discharge through the vagina and will be accompanied by pain in the lower abdomen. Women with embryonic abortion should have a timely clearance procedure to avoid intrauterine residue. If the embryo has been in intrauterine arrest for two weeks at the time of discovery, it is called an indolent abortion, in which case it is recommended that it is safer to terminate the pregnancy in hospital because of the risk of coagulation dysfunction, which can lead to post-abortion hemorrhage.
