Why does bleeding occur during sexual intercourse right after menstruation has ended?

Generally, bleeding during sexual intercourse right after menstruation may be caused by factors such as residual menstrual blood, vaginal dryness, vaginitis, cervicitis, endometritis, and others. The solution depends on the specific cause and prompt medical attention is advised, following the doctor's instructions for treatment. Detailed information is as follows:

1. Residual Menstrual Blood: At the very beginning after menstruation ends, the endometrium might not have fully healed, and there may be a small amount of remaining menstrual blood within the uterine cavity. Sexual activity might stimulate the discharge of this residual blood, causing bleeding. Usually, no special treatment is required, and monitoring the bleeding is sufficient. If the bleeding persists or is accompanied by other discomfort symptoms, medical attention should be sought promptly.

2. Vaginal Dryness: After menstruation, hormone levels in a woman's body may not have fully recovered, leading to decreased vaginal secretions and vaginal dryness. During sexual intercourse, vaginal dryness may cause friction-induced bleeding of the vaginal wall. Using lubricants can help increase vaginal moisture and reduce friction. Additionally, maintaining good personal hygiene is important to avoid infections. If symptoms persist,

3. Vaginitis: Vaginitis refers to inflammation of the vaginal mucosa and submucosal connective tissue, which may be caused by pathogenic infections such as bacteria or fungi. During sexual intercourse, irritation and friction from pathogens may lead to vaginal bleeding, accompanied by increased vaginal discharge. Antimicrobial and pain-relief treatments can be administered under medical guidance using medications such as metronidazole suppositories, Baofukang suppositories, clotrimazole vaginal tablets, etc.

4. Cervicitis: Cervicitis refers to inflammation of the mucous membranes of the cervix and cervical canal, which may be caused by pathogenic infections, irritation from chemical substances, or tissue damage. During sexual intercourse, stimulation of the cervix may lead to bleeding, accompanied by itching of the external genitalia. Anti-infective and anti-inflammatory treatments can be administered under a doctor's guidance using medications such as levofloxacin hydrochloride capsules, cefixime capsules, and Fuke Qianjin tablets.

5. Endometritis: Endometritis is an inflammation of the endometrium, which may be caused by pathogenic infections or infections following intrauterine surgical procedures. During sexual intercourse, stimulation of the endometrium may lead to bleeding, often accompanied by fever. Medications should be taken under medical guidance, such as amoxicillin granules, ibuprofen suspension, ribavirin granules, etc., to provide antiviral and anti-inflammatory effects.

Maintaining good personal hygiene habits in daily life is important, and the use of cleansing products containing irritating chemicals should be avoided.
