Why is the menstrual period long after medication abortion?

Patient's question:

What should I do if I get pregnant unexpectedly? The harm is relatively small. Why is the menstrual period long after taking medication for abortion?

Doctor's answer:

The bleeding time after medication abortion is relatively long, usually around 2 weeks; if the bleeding exceeds 3 weeks, it is important to seek medical attention promptly.
According to regulations, two weeks after the expulsion of the gestational sac, women should return to the medication abortion facility for a follow-up examination. If bleeding has not stopped by then, a urine pregnancy test and ultrasound examination should be conducted. If incomplete abortion is diagnosed, a dilatation and curettage (D&C) should be performed, after which vaginal bleeding will typically stop within 10 days. If the bleeding persists due to incomplete shedding of the decidua but is not excessive at the time of consultation, it may be treated with Motherwort ointment or the Chinese herbal decoction Shenghua Tang. Intramuscular administration of oxytocin can also be used to promote uterine contractions and expel residual decidua tissue. Patients with bleeding exceeding menstrual volume generally require a D&C. It is important to note that some women undergoing medication abortion may suddenly experience a significant increase in bleeding, possibly several times the amount of a normal menstrual period, accompanied by large blood clots. This is caused by the incomplete detachment and expulsion of embryonic tissue, and immediate medical attention is required, including a D&C to stop the bleeding.
Some individuals believe that treating prolonged bleeding after medication abortion with hemostatic medication is sufficient, but this is absolutely incorrect. Hemostatic medications work by altering the body's coagulation mechanism to stop bleeding but cannot remove residual tissue from the uterine cavity, thus failing to address the root cause. Bleeding will only stop when the embryonic tissue in the uterine cavity is largely expelled and uterine contractions are effective.
