Introduction
The term "first night" refers to the first time engaging in sexual intercourse. Persistent vaginal bleeding after the first sexual experience may be caused by factors such as medication effects, onset of menstruation, vaginal wall laceration, cervicitis, or cervical polyps. If any discomfort occurs, prompt medical attention is recommended. Women should undergo regular gynecological examinations in daily life, maintain good personal hygiene, and avoid unhygienic sexual practices.
Generally, the "first night" refers to the first instance of sexual intercourse. Persistent vaginal bleeding after the first sexual experience may be caused by medication effects, onset of menstruation, vaginal wall laceration, cervicitis, cervical polyps, etc. If discomfort occurs, it is recommended to seek medical attention promptly. Specific causes are analyzed as follows:
1. Medication effects
Taking medications such as emergency contraceptive pills before or after sexual intercourse may cause changes in hormone levels, leading to vaginal bleeding for a period after taking the medication. Usually, no special treatment is required, and the bleeding will stop spontaneously within several hours to a few days.
2. Onset of menstruation
If the first sexual intercourse occurs just before or at the beginning of menstruation, the vaginal bleeding might be due to the start of the menstrual period. No special treatment is generally needed; maintaining genital hygiene and preventing infection are advised.
3. Vaginal wall laceration
Vaginal wall lacerations are usually caused by overly vigorous movements or insufficient lubrication during sexual intercourse. Symptoms may include pain and swelling. Patients can follow medical advice to use medications such as erythromycin ointment, povidone-iodine solution, or kangfuxin liquid for treatment.
4. Cervicitis
Cervicitis is an inflammation of the cervix, which may be caused by bacterial or viral infections. During sexual intercourse, the inflamed area may become irritated and bleed. Other symptoms may include increased vaginal discharge, unpleasant odor, and abdominal pain. Patients should follow medical guidance to use medications such as azithromycin dispersible tablets, cefixime capsules, or polyacrylate formaldehyde sulfonate suppositories for treatment.
5. Cervical polyps
Cervical polyps are benign growths on the cervix, often caused by chronic inflammatory stimulation. During sexual intercourse, these polyps may become irritated and bleed. Additional symptoms may include bloating and pain. Under a doctor's guidance, patients may use medications such as ornidazole tablets, gaiyanping tablets, or guizhi fuling capsules for treatment.
Women should undergo regular gynecological examinations in daily life, maintain personal hygiene, and avoid unhygienic sexual practices.
