Can you get pregnant on your period​?Pregnancy is not possible during menstruation, but sexual intercourse is prohibited during menstruation.
Menstruation refers to the bleeding that occurs after the shedding of the endometrium due to the withdrawal of progesterone caused by the periodic changes in hormone levels secreted by the ovaries. During the menstrual period, the level of estrogen is low, the follicles are small, and they have not fully developed, so there is no ovulation. Therefore, sperm cannot meet the egg and there is no possibility of pregnancy.
After entering the vagina, sperm follow the vagina into the cervical canal, enter the uterine cavity from the cervical canal, and then swim from the uterine cavity to the fallopian tube, where they meet the egg and have the possibility of fertilization and pregnancy.

Sperm can only exert its function when it combines with the egg in the body. The fertilization of sperm and egg can only occur when the follicle ovulates, and the discharged egg meets and combines with sperm to form a fertilized egg. The fertilized egg travels to the uterine cavity and implants and implants in the endometrium. The ovulation period is about 14 days before the next menstrual cycle, which is the middle of two menstrual periods.
Sperm and egg are prerequisites for pregnancy, and eggs are not released during menstruation, so conception cannot occur during menstruation. During the menstrual period, due to the need to discharge menstrual blood from the body, the cervix is in an open state, which weakens the body and reduces resistance. So during the menstrual period, sexual intercourse is prohibited because it can easily lead to bacterial invasion, causing various gynecological diseases, as well as increased menstrual flow or prolonged periods.
