A month after the abortion stomach pain, in the absence of menstruation, then the vast majority is due to cervical adhesions. Because after the cervical adhesion, there is no way for the menstrual blood to flow out, so there is a swelling of the stomach, and the pain is more serious, you need to go to the hospital for ultrasound examination. If the ultrasound determines that there is fluid in the uterus, then the stomach pain is caused by cervical adhesion, and cervical dilatation should be done under aseptic operation, so that the abdominal pain will be relieved immediately after the menstrual blood flows out. After the operation, anti-inflammatory treatment will be given to prevent the cervix from sticking together again and causing stomach pain. Therefore, most of the stomach pain after abortion is caused by cervical adhesion.
