I don't have sex on the first day of my period.

Having sex on the first day of a woman's menstruation may cause infection, abdominal pain, and abnormal vaginal bleeding. This is because the woman has her period and the uterine wall has begun to shed significantly. If you have sex during this time, the squeezing effect of the male penis on the vagina is likely to cause retrograde menstruation or intrauterine infection. When the penis is erect, semen can be secreted, which will cause a certain degree of irritation to the female uterus and promote uterine contractions, which may cause significant abdominal pain during menstruation.

Because abnormal contraction of the uterus can cause changes in the rate at which the uterine wall falls off, it may also cause changes in menstrual bleeding. As long as the body does not have any abnormal reaction during sexual intercourse, there is nothing wrong. Just pay attention to not having sexual intercourse during the menstrual period.

If you have sex on the first day of your period and there is no obvious discomfort such as lower abdominal distension and pain, vulvar itching, abnormal menstrual flow, etc., you can observe it, which means that having sex may not have any adverse effects on your body. If you experience lower abdominal distension and pain after intercourse, or an increase or decrease in menstrual volume, have an ultrasound examination as soon as possible to check the condition of your pelvis and uterus. According to the test results, a customized treatment plan is selected. In addition, pay attention to rest, keep the vulva clean, and keep warm. It is recommended to pay attention to the hygiene of the living environment of the couple and not to have sex during the menstrual period.

If the patient is on the first day of menstruation, the amount of vaginal bleeding is small, and special attention is paid to hygiene during intercourse, it generally will not cause any impact on the patient, so there is no need for special treatment. If the patient has a lot of bleeding on the first day of menstruation, the probability of infection during intercourse at this time will be very high. The patient can protectively use Chinese herbal medicines that clear heat and reduce fire, or antibiotics to prevent infection. You can also observe that if the patient does not experience abdominal pain, vaginal bleeding, foul odor, etc., it means there are no signs of infection and no medication is needed.
