Can I have sex on the first day of my period?

Girls have their periods every month, and they are not allowed to have sex during their periods, and try not to have sex on the first day of their periods. Although the period before and after menstruation is a safe period, pregnancy can still occur if something unexpected happens, and it is very harmful to the female body. On the first day after menstruation, the blood stasis has not been cleared up, and it is easy to cause infection, which is not good for both husband and wife.

Generally speaking, the 3 days after menstruation ends and the 3 days before menstruation are an absolutely safe period, and you will not get pregnant even if you do not take any contraceptive measures. This is mainly because there is no ovulation and the uterus is not ready for implantation at this time.

Generally speaking, it is not easy to get pregnant within 8 days after menstruation.

A woman's ovulation day is about 14 days before the next menstrual period. The ovulation period, which includes the ovulation day, the 5 days before and the 4 days after, is about 10 days in total. Except for the menstrual period and ovulation period, the rest of the time is the safe period. The key to calculating the safe period is to determine the woman's ovulation date. Menstruation and ovulation change cyclically, and there is a close relationship between the two. If you understand the changing patterns of the two, you can determine the ovulation date through indirect methods. There are many ways to determine the ovulation date, such as calculating based on the menstrual cycle, measuring basal body temperature, and observing vaginal secretions. Most women choose to calculate the ovulation period based on the menstrual cycle, but this method is only suitable for women with normal menstrual cycles.

The prenatal check-up in the second trimester is not done once, but several times at different time periods. Generally, there are about four examinations in the second trimester. These four examinations should be done approximately every 1 month. Don’t think that the time is too frequent. This is a period of rapid growth of the fetus, and fetal examinations are definitely necessary. These examinations can help us understand the growth of the fetus and whether there are any diseases.
