But this largely depends on her cycle. For a 28 days cycle, starting from the first day, the day 14 of menstrual period can be the most fertile. This means that if a sperm gets deposited on day 10 (which can usually live till day 14), a woman can conceive when she has a fertile cervical mucus. A sperm can also conjugate with her egg from the 15th day upto the 19th day of the cycle. If you want to know the most fertile days, go two ways- backward 72 hours and forward 24 hours.

Menstrual Cycle, Ovulation And Pregnancy Can Be A Complex Outcome

Although it may seem simple, menstrual cycle and conception can be a tricky phenomenon for the average woman. Ovulation, the time when your egg is released, is crucial for experiencing pregnancy. But pregnancy is not restricted to ovulation alone. The sperm, which has to combine with the egg (fertilization) to result into conception, can survive in a woman’s body for about 4-7 days.



Ovulation generally happens between the 14-16th day before your next menstrual period begins. So pregnancy can happen even if you have had sex(few days) before and after ovulation. Women with regular menstrual cycles (26-32 days) have the highest chances of getting pregnant between 8-19th day of their cycles.It is not easy to predict ovulation, and pregnancy, when you have irregular periods.

Ovulation, which is the key to pregnancy, can be determined with great approximation using some indispensable tools like recording body temperature and analyzing cervical fluids. Usually, a combination of methods is implemented to apply natural family planning.

However, it is not 100% safe to rely on natural family planning and have unprotected sex even with the most precise tools because mother nature may have something else in store than what you have planned for!
