Whether the symptoms of bleeding and abdominal pain on the 4th day after abortion are normal or not should be judged according to the severity of the symptoms. A small amount of vaginal bleeding and mild stomach pain on the 4th day after abortion is normal, and the uterine lining will shed to some extent after abortion, so a small amount of bleeding within a week can be observed for the time being. Mild lower abdominal pain may be related to contractions that promote uterine recovery, so this is not abnormal. However, if the bleeding becomes heavier or exceeds the amount of menstruation, the abdominal pain is obvious, and the abdominal pain becomes unbearable, it is definitely abnormal, and you need to go to the hospital for ultrasound to clarify whether the uterus is not recovering well or the abortion is incomplete, and then treat the symptoms according to the result.
