The number of days in your cycle is calculated by counting the number of days from the beginning of one period to the beginning of the next period. If you have a short cycle, for example 21 days, and you bleed for 7 days, then you could ovulate right after your period.
Generally, a woman ovulates 11 to 21 days after the end of her last period or from 12 to 16 days before she expects her next period to begin. During ovulation, an egg is only available for fertilization for 12 to 24 hours. However, since sperm can live in the body for up to five days, it is possible to get pregnant right after ovulation. A missed period may signal a pregnancy.
