Bleeding after abortion will end within 3-7 days and will not affect your health. 3 days of bleeding again is considered within the normal range, as the lining will not return to its normal form at once and a process is needed. There is still a small amount of lining in the uterine cavity after the gestational sac is expelled, and the uterus slowly contracts from a pregnant state to a non-pregnant state, which also requires a process, and may cause bleeding or pain during the contraction. As long as the amount of bleeding is not particularly heavy, not similar to the amount on the second day of menstruation, it is normal to observe the bleeding for 4 days, as long as it ends within 7 days. However, if there is still bleeding beyond 7 days or even up to the 10th day, this time suggests that there is a chance of residual uterine asystole, and it is necessary to go to the hospital for a follow-up ultrasound to determine whether there is any abnormality in the uterine cavity, and according to the situation of the oral medication treatment.
