Ectopic pregnancy is the common term for ectopic pregnancy, and conservative treatment of ectopic pregnancy refers to medication. During the conservative treatment of ectopic pregnancy, vaginal bleeding is normal. The mechanism of action of ectopic pregnancy medication is the use of chemical drugs to inhibit the proliferation of trophoblast cells, destroy the villi, and cause necrosis, shedding and absorption of embryonic tissue. When the medication works, the serum HCG level in the patient’s body will drop, which will lead to the detachment of the meconium and vaginal bleeding. However, if the tubal pregnancy ruptures during conservative treatment and severe abdominal pain occurs in addition to vaginal bleeding, this is a sign of internal bleeding in the abdominal cavity, which is an acute abdominal condition and requires emergency surgery.
