Women who bleed after intercourse and have stomach pains may suffer from chronic cervicitis, cervical polyps, bleeding caused by irritation after intercourse, and stomach pains caused by upstream infection. In this case, women should undergo gynecological examination and perform routine leucorrhea examination to find out whether they have cervical polyps or cervical erosion. If it is cervical erosion, cancer screening and TCT and HPV tests should be performed to exclude precancerous lesions of the cervix. If the bleeding after intercourse is caused by inflammation, such as cervical polyps or cervical erosion, timely treatment should be given to cervical erosion, cervical polyp removal surgery should be performed, and anti-inflammatory and hemostatic drugs should be given orally after the surgery, and intercourse should be allowed only after the inflammation is cured.
