If there is pain in the stomach and no vaginal bleeding three days after abortion, this is mostly due to pelvic inflammatory disease caused by pathogenic bacteria infection. It is recommended to go to the hospital for gynecological examination to understand the degree of inflammation and give anti-inflammatory treatment in time. If there is pain in the stomach and vaginal bleeding three days after the abortion, it is most often caused by incomplete abortion. When the embryonic tissue remains in the uterus, the residual tissue is stripped from the uterine wall, stimulating the contraction of the uterus and bleeding from the stripped surface, causing pain in the lower abdomen. It is recommended to go to the hospital for ultrasound examination, and according to the results, timely clearance surgery is clinically given to avoid causing infection, and anti-inflammatory drugs must be given to prevent infection after surgery.
