Can you get pregnant outside of ovulation period?

Generally, the possibility of becoming pregnant outside the ovulation period depends on whether ovulation is regular and the lifespan of sperm. If ovulation is regular and far from the ovulation period, pregnancy is unlikely; however, if ovulation is irregular or nears the ovulation period, there is still a chance of becoming pregnant. A detailed explanation is as follows:

If a woman's ovulation is regular and she is not in her ovulation period, the ovaries have not released an egg. During this time, even with sexual intercourse, sperm cannot combine with an egg, making pregnancy unlikely. For the purpose of contraception, the probability of pregnancy is low during this phase, but precautions should still be taken to avoid unexpected situations.

If a woman's ovulation is irregular, with early or delayed ovulation, what was originally thought to be a non-ovulatory period might actually be the ovulation period. Alternatively, even if it is not the exact ovulation day, if it is close to the ovulation period, sperm can survive in the female body for 2-3 days and still have the chance to combine with an egg released later, thus making pregnancy possible.

To meet the needs of either conception or contraception, ovulation test strips and basal body temperature monitoring can be used in daily life to accurately determine the ovulation period. Women with irregular menstrual cycles should also observe changes in vaginal discharge to assist in determining the ovulation period.
