It is possible to get pregnant without having sex during a woman’s ovulation period.
For women, the mature egg can survive in the fallopian tube for 1 to 2 days after ovulation, and the sperm can survive in the female vagina for 2 to 3 days, so even if you do not have intercourse during the ovulation period, the sperm and the egg may still combine to form a fertilized egg, and pregnancy may occur.
Safe period birth control is only relatively safe for women who normally have regular menstruation, but for women who normally have irregular menstruation, this type of birth control is not absolutely safe.
For women who do not need to prepare for pregnancy, they should not take any chances and should use condoms and IUDs to avoid unwanted pregnancy.
