The normal menstrual cycle is about 30 days and the menstrual period lasts 3-5 days, so it is a safe period just after menstruation. There is no egg discharged during the safe period, and its will not lead to pregnancy. However, some people have a short menstrual cycle, for example, the menstrual cycle is 24 days, and the period lasts for 6-7 days, so when the period just clears, it belongs to the ovulation period and there is a possibility of pregnancy. So whether or not you can get pregnant needs to be determined by your own menstrual cycle and also by the duration of your period, etc. If you don’t want to get pregnant, you need to use birth control, you can use condoms or use contraceptive rings. However, you should not use birth control pills because they have many side effects and can cause endocrine disorders. It is best to have intercourse only 2-3 days after the menstruation. If you have intercourse too early, there will be residual blood in the vagina, which will easily cause rebleeding and gynecological infection.
