What should I do if I had sexual intercourse during my menstrual period?

If a patient engages in sexual intercourse during menstruation, measures such as cleaning, medical examination, and medication can be taken to reduce potential harm to the body. However, sexual activity during menstruation is generally not recommended, as it may affect health. Specific recommendations are as follows:

1. Cleaning: After intercourse during menstruation, the patient should first wash the external genitalia with warm water, then use a feminine cleanser for a second cleanse. Rinse thoroughly with clean water afterward, dry carefully, and change into clean underwear.

2. Examination: If the patient experiences symptoms such as abdominal bloating or genital pain, prompt medical consultation is advised. An ultrasound (B-scan) can be performed to evaluate the condition of the uterus and check for any abnormalities in the endometrium.

3. Medication: After completing auxiliary examinations such as ultrasound, if the doctor confirms gynecological conditions like vaginitis, the patient may take anti-inflammatory and antibacterial medications as prescribed—such as metronidazole or erythromycin—to alleviate local inflammation.
