Generally speaking, you can’t get pregnant when you’re on your period, but you have to decide if the vaginal bleeding is from your period.
Aunt means menstruation. If the egg is not fertilized after intercourse, the corpus luteum will degenerate and atrophy 9 to 10 days after ovulation, and then menstruation will occur, so menstruation means no pregnancy. However, if a small amount of vaginal bleeding occurs at the time of menstruation, it may not necessarily be menstruation, but may also be caused by pre-menstrual abortion, which requires medical attention.
Women who have the desire to have children may choose to have intercourse during ovulation under the guidance of a doctor to increase the chances of conception. Also take folic acid on time as prescribed by your doctor, which can prevent the risk of neural tube malformation in the fetus. If you do not intend to get pregnant, take proper contraceptive measures.
