Female bleeding refers to local bleeding in the vagina or external genitalia during or after sex. Generally, the amount of bleeding is not large, and only a very small number can cause heavy bleeding. There are many reasons for female bleeding, which can be roughly divided into two categories: improper sex and local organic lesions of the female reproductive system, with the latter being the most common.

1. Endometriosis Some endometriosis grows in the cervix and appears as blue-purple nodules. If this blue-purple ectopic nodule is encountered during sexual intercourse, it will cause bleeding. The amount of bleeding is generally small and dark red, and abdominal pain often occurs after intercourse.

2. Bleeding after cervical cancer is its earliest symptom. Because there are more small blood vessels and more fragile tissues in the cancer lesions, the capillaries will rupture and bleed due to damage every time after sexual intercourse. If the cancer progresses, it will bleed more easily.

3. Cervical polyps: Cervical polyps may occur due to long-term stimulation of the cervix by chronic inflammation. Single or multiple small granulation tissues with pedicles grow at the cervical opening, looking like yellow sprouts, and the larger ones are as big as a finger. Polyps are fragile and tender, and will bleed if touched, so bleeding may occur after sexual intercourse. This bleeding is usually bright red.

4. Cervicitis (cervical erosion) 90% of married women suffer from cervicitis. Cervicitis is divided into three types: mild, moderate and severe according to the degree of cervical erosion. For patients with moderate or severe cervical erosion, the rubbing of the cervix by the glans of the male's penis during sexual intercourse may cause injury and bleeding. Because the amount of bleeding is small, it does not flow out immediately but accumulates in the vagina, and the color of the blood changes from fresh to old. Therefore, when the blood flows out the next day, it is dark red.

5. Pelvic inflammatory disease Pelvic inflammation can cause pelvic congestion. If the endometrium is congested and edematous, the congested endometrium may bleed after intercourse, but this chance is rare.
