However, it is usually less than or equal to the amount of menstrual flow, accompanied by blood clots. Once the expulsion of the pregnancy tissue is complete, the abdominal pain decreases or even disappears. There is also less blood flow and the bleeding usually stops in 5-7 days. It is usually expelled after 6-8 hours, but some are expelled within 24 hours and even within three days.
