You can’t usually get pregnant if you are not ovulating. Because when you are not ovulating, no egg is released and you will not get pregnant. The 14 days before your next period is the day of ovulation, and the 5 days before and 4 days after the day of ovulation, including the day of ovulation, a total of 10 days is called the ovulation period. If your period is irregular, it can also affect ovulation and you cannot be sure of the ovulation period. If you do not use contraception, there is a possibility of pregnancy. You can generally use ovulation test strips to monitor ovulation, or you can go to the hospital for an ultrasound to observe the development of follicles. If you do not intend to get pregnant, you should have intercourse during the safe period, you can also use condoms or the contraceptive ring for contraception, and you should have regular medical checkups.
