How many days after menstruation can you have sex?

　　From the perspective of physiological recovery: after women’s menstruation ends, Uterus And the vagina needs some time to recover. Generally speaking, when menstruation has just ended, there are still broken blood vessels and glandular ducts on the surface of the uterine cavity, and there is still bleeding from tiny blood vessels. The new endometrium has just begun to grow, and the surface is not yet covered by epithelium. Having sex at this time can easily cause the wound that has not been completely repaired to be damaged again, causing vaginal bleeding again, and may also increase the risk of infection. It is usually recommended to wait 2-3 days after menstruation is clear before having sex. This can give the body enough time to recover and reduce the possibility of infection and bleeding.

　　Impact of individual differences: There are differences in the body’s ability to recover among different women. Some women are in good physical condition and recover quickly after menstruation. They may basically return to normal 2 days after menstruation. ； Some women are weak, or have heavy bleeding during menstruation and a long duration. The recovery time may be relatively prolonged, and it may take 3 days or even longer before they can have sexual intercourse. In addition, factors such as age and living habits will also affect the body’s recovery speed.

Tips for judging the safe period after menstrual period

　　Calendar method: For women with regular menstrual cycles, the calendar method can be used to calculate safe periods. Generally speaking, a woman's ovulation day is usually about 14 days before her next menstrual period. The ovulation day and the 5 days before and 4 days after it are collectively called the ovulation period. Except for the menstrual period and ovulation period, the rest of the time is the safety period. For example, a woman's menstrual cycle is 28 days, and the first day of this menstruation is the 1st, then the next menstrual period may be around the 29th, and the ovulation day will be around the 15th. The 10th-19th is the ovulation period. Apart from the menstrual period and ovulation period, other times are safe periods. But this method is not suitable for women with irregular menstrual cycles.

　　Basal body temperature method: Basal body temperature refers to the body temperature measured after 6-8 hours of sleep and before any activity. During the menstrual cycle, a woman's basal body temperature fluctuates with changes in hormone levels. Generally, before ovulation, the basal body temperature is low. After ovulation, due to the effect of progesterone, the basal body temperature will increase by 0.3-0.5°C, and this will continue until the next menstrual period. By measuring and recording the basal body temperature after waking up every morning, the ovulation date can be determined based on changes in body temperature, and the safe period can be calculated. It should be noted that measuring basal body temperature needs to be done at the same time every day, and there should be no activities before the measurement, otherwise the accuracy of the measurement results will be affected.

　　Cervical mucus observation method: As the menstrual cycle changes, the properties of cervical mucus will also change. Before ovulation, the amount of cervical mucus gradually increases, becomes thin, transparent, and stringy, reaching more than 10cm. ； After ovulation, the amount of cervical mucus decreases, becomes thicker, turbid, and becomes less silky. By observing changes in cervical mucus, you can roughly determine the date of ovulation and thus determine the safe period. However, this method requires a certain amount of experience and careful observation, and may be difficult for beginners.
