Tracking your ovulation is essential when trying to get pregnant. Ovulation occurs when a women release a mature egg from the ovary to the fallopian tube, making it available for fertilization. The released egg is only viable for 12 to 24 hours after leaving the ovary, and fertilization must occur during this time period in order to achieve pregnancy. Unlike the egg, sperm can survive up to 3 days in the fallopian tubes, waiting for the egg to arrive. Tracking your ovulation will help you determine the best days during your monthly cycle to get pregnant. The best days to have intercourse are a few days following ovulation and on the day of ovulation and two days after ovulation11 (ASRM and SREI. 2017. fertstert.org/article/S0015-0282(1662849-2/fulltext text: Fertility and Sterility popup: yes)).
