In the case of medical abortion, it will cause some bleeding and also cause weakness, but it is more likely to cause a cold, so we must pay attention to it. In fact, after 3 days, you can take a normal shower, wash your vulva every day, and change your underwear every day. After 10 days, you must review the ultrasound, because there is a 40% chance of failure of medical abortion, to avoid the residual tissue in the uterine cavity for too long, which can cause long bleeding, but also cause the chance of infection, you must remember to review.
