It is not easy to get pregnant one week before menstruation. If menstruation is regular, ovulation is 14 days before the next menstrual period, and the egg survives to have the ability to be fertilized for 24 hours, so it is not easy to get pregnant one week before menstruation.
Women’s menstrual cycle can be divided into follicular phase, luteal phase, menstrual phase, ovulation is usually about 14 days before the onset of menstruation, a week before menstruation is the luteal phase.
The luteal phase is already after ovulation, and if the egg is discharged and cannot be fertilized within 24 hours, it is usually impossible to get pregnant, so having sex in the luteal phase is not easy to get pregnant.
The week before menstruation is not easy to get pregnant, but there is also the possibility of pregnancy, if you do not intend to get pregnant, it is recommended to do a good job of contraception, to avoid damage to the body due to abortion and so on.
