If there is intermittent vaginal bleeding all the time after abortion, there may be the following three reasons: First, some tissues remain in the uterine cavity after abortion, that is, the abortion is not clean, it is the most common reason leading to intermittent bleeding after abortion, and doing vaginal ultrasound as well as taking blood tests for blood HCG can get a clear diagnosis. Secondly, there may be infection. After abortion, the resistance drops, if you don’t pay attention to rest and keep the vulva clean, it is very likely to cause infection. Through the gynecologist’s gynecological examination, blood test, CRP, etc., to see whether the blood test has increased, it can be clear that there is no infection. Thirdly, the hormone level drops after abortion, resulting in low estrogen and progesterone levels, affecting the repair of the uterine lining, resulting in intermittent vaginal bleeding, supplementation of estrogen and progesterone treatment bleeding will soon stop.
