In addition, it should be noted that at any stage of the menstrual cycle, it is necessary to take safe and effective contraceptive measures to prevent unwanted pregnancies from causing harm to the body. Although the menstrual period has just cleared and there is no development of dominant follicles yet, it does not mean that there are no special circumstances, such as a short menstrual cycle, a longer period of menstrual travel, and the menstrual period has just cleared and entered the risky stage of ovulation. Meanwhile, sperm can survive for 24 to 72 hours after entering the reproductive tract.

Sexual intercourse should be prohibited during menstruation, and if you feel unwell, you should go to the hospital in time for examination and follow the doctor’s instructions to deal with the treatment.
