How long after taking misoprostol tablets is the fetal sac expelled?

Patient's question:

Medical Description: Took misoprostol tablets at 5 a.m. Approximately what time can the fetal sac be expelled?
History of Treatment and Effect: Previously never pregnant, in good health.
Help Needed: Does the expelled blood clots definitely contain the fetal sac? ??
Have been experiencing abdominal pain for several hours after taking the medication. Is this a normal phenomenon?
If the medication abortion is incomplete, is it necessary to undergo a uterine clearance promptly? ??
Thank you very much, doctor.

Doctor's answer:

Hello, generally the gestational sac starts to be expelled within 3 days, but individual differences should also be considered. The average bleeding duration after the gestational sac is expelled in medication-induced abortion is 18 days, with some cases having longer bleeding periods. The reasons for prolonged bleeding may include incomplete decidual shedding, which affects uterine contraction and hemostasis; or incomplete expulsion of the gestational sac, leading to incomplete abortion. In a few cases, it may be due to infection after medication-induced abortion, resulting in endometrial inflammation. It is recommended to undergo an ultrasound examination.
If the gestational sac cannot be expelled for an extended period, it is best to seek medical attention promptly for an ultrasound examination. If necessary, surgical uterine evacuation may be performed.
