How long does brown discharge last after a medical abortion?
Under normal circumstances, brownish discharge after a medical abortion may last for 7–14 days, which is part of the normal process of endometrial shedding. Detailed analysis is as follows:

If the pregnancy tissue is completely expelled during the medical abortion and uterine contractions are good, the amount of brownish discharge will gradually decrease, with no significant abdominal pain, foul odor, or other discomforts. In such cases, the discharge usually resolves within about 7 days. This indicates a smooth uterine recovery process without retained tissue in the uterine cavity, and the body is gradually returning to normal. There is generally no need for excessive concern—continued observation is sufficient.
If the expulsion of pregnancy tissue is incomplete, residual tissue remains in the uterine cavity, or uterine contractions are weak, the amount of brownish discharge may not decrease but instead increase, accompanied by symptoms such as abdominal pain, fever, or foul-smelling discharge. In these cases, the discharge may persist for 14 days or longer, which should not be ignored. Retained tissue can easily lead to infection and impair uterine recovery. Prompt medical evaluation is necessary, and in some cases, a procedure to clear the uterine cavity (such as dilation and curettage) may be required.
In daily life, maintain external genital hygiene, frequently change into breathable underwear, and avoid tub baths and sexual intercourse. Get adequate rest and avoid overexertion. Eat a diet rich in iron and high-quality protein. Seek immediate medical attention if abnormal discharge persists.
