What causes pinkish blood after intercourse, and what should I do if it's not like a regular menstrual period?

"Big sister" refers to menstruation. Pinkish bleeding after intercourse that does not resemble a regular menstrual period may be caused by vaginal mucosal injury, cervicitis, cervical polyps, polycystic ovary syndrome (PCOS), endometriosis, or other conditions. Appropriate treatment should be determined based on the underlying cause.

1. Vaginal Mucosal Injury

Excessively rough sexual activity may damage the vaginal mucosa, resulting in bloody discharge. Minor bleeding typically resolves spontaneously and is not a cause for concern; however, sexual intercourse should be avoided for a short period.

2. Cervicitis

When the cervix becomes infected with inflammation, it may lead to congestion and swelling of the cervical mucosa. During intercourse, stimulation of the inflamed mucosa can cause rupture, leading to abdominal pain and bleeding. It is recommended to follow medical advice and use medications such as amoxicillin capsules, azithromycin tablets, or cefixime tablets to control inflammation and relieve symptoms.

3. Cervical Polyps

Cervical polyps have rich surface blood vessels. During intercourse, irritation or trauma to these vessels may easily cause local bleeding, which often appears pink or light red—distinct from the dark red blood typical of menstruation. It is recommended to visit a hospital for polyp removal via procedures such as hysteroscopic electrocautery or cervical conization.

4. Polycystic Ovary Syndrome (PCOS)

This condition may be accompanied by cervical erosion. If the cervical tissue is stimulated or injured during intercourse, abnormal bleeding may occur, often along with irregular menstrual cycles. Under medical guidance, medications such as cyproterone acetate tablets, clomiphene citrate tablets, or dydrogesterone tablets may be prescribed to improve symptoms.

5. Endometriosis

Endometriosis may cause adhesions and inflammation among pelvic organs and tissues. Sexual activity may injure or irritate the cervix, uterus, or pelvic tissues, leading to bleeding. This may also be accompanied by dyspareunia (painful intercourse) and menstrual irregularities. Under medical supervision, medications such as cefixime tablets, progesterone capsules, or dienogest tablets may be used to reduce infection, inflammation, and alleviate symptoms.

If pinkish bleeding occurs after intercourse but does not appear to be a normal menstrual period, it is advisable to temporarily avoid sexual activity, get adequate rest, and avoid spicy or irritating foods. If symptoms persist, prompt medical evaluation and active treatment are necessary.
