Why do I bleed again after menstruation is clean and have intercourse?

Bleeding after clean menstruation may be related to factors such as cervicitis, endometrial polyps, ovulation bleeding, hormone level disorders, or cervical lesions. The cause can be determined through gynecological examination, hormone testing or imaging examination, and drug treatment, physical therapy or surgical intervention can be taken based on the results.

1. Cervicitis

Cervicitis is an inflammatory reaction of the cervical mucosa, often caused by bacterial or viral infection. Mechanical stimulation during intercourse may cause congestion, damage to the cervical mucosa and bleeding, which may manifest as contact bleeding and may be accompanied by yellow discharge or distension of the lower abdomen. It is necessary to follow the doctor's advice to use anti-uterine inflammation tablets, Baofukang suppository or doxycycline hydrochloride tablets and other drugs, and avoid sexual intercourse stimulation.

2. Endometrial polyps

Endometrial polyps are benign lesions caused by local overgrowth of the endometrium. Uterine contractions during intercourse may pull the polyps and cause bleeding. Bleeding that is light and bright red in color may be accompanied by irregular menstrual cycles. The diagnosis can be confirmed through hysteroscopy. Smaller polyps can be adjusted by taking progesterone capsules, while larger polyps require hysteroscopic resection.

3. Bleeding during ovulation

Breakthrough bleeding caused by a brief drop in estrogen during ovulation may occur 7-10 days after menstruation, and sexual intercourse stimulation will aggravate the bleeding. It usually lasts for 2-3 days and is in small amounts. You can take estradiol valerate tablets to regulate hormone levels and reduce strenuous exercise during this period.

4. Hormone level disorders

Staying up late or being stressed for a long time may lead to insufficiency of the corpus luteum, and sexual intercourse may easily cause bleeding when the endometrium is not fully repaired. It may be accompanied by low menstrual flow or prolonged menstrual period. Six items of sex hormones need to be checked. Follow the doctor's advice to use dydrogesterone tablets or estradiol cyproterone tablets for cycle conditioning.

5. Cervical lesions

Persistent infection with high-risk HPV may lead to cervical intraepithelial neoplasia, and bleeding after intercourse is a common early symptom. TCT and HPV screening are required. For CIN 1, vaginal interferon suppositories can be used. For CIN 2-3, cervical conization is required, and regular postoperative reviews are required.

It is recommended to record the bleeding time, amount and accompanying symptoms, and avoid using tampons to irritate the vagina. Sexual intercourse should be prohibited during bleeding after intercourse. Choose pure cotton breathable underwear and change it daily. Adding citrus fruits and animal livers rich in vitamin C to your diet can help enhance blood vessel elasticity. If the bleeding lasts for more than 3 days or is accompanied by severe abdominal pain or fever, you need to seek medical treatment immediately to rule out emergencies such as ectopic pregnancy. Maintain a regular daily schedule to avoid endocrine disorders caused by excessive dieting and weight loss.
