Under normal circumstances, a woman who uses medication to terminate a pregnancy after an unwanted or unplanned pregnancy is called a medication abortion. After the abortion, the bleeding usually clears in about 7-10 days. If the bleeding suddenly increases 12 days after the abortion, you should consider whether there are two conditions: the first one is the increase of bleeding caused by the poor recovery of uterine contraction. The second, consider whether there is an increase in bleeding caused by the stimulation of intrauterine residues. In this case, you have to go to the gynecology department of the hospital to review the ultrasound to see the recovery of uterine contraction and the presence of residues, then according to the results of the ultrasound to treat the symptoms.
