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.
The first day of your period, when you start bleeding, is counted as the first day of your cycle. If you have a 28-day cycle, you'll usually ovulate some time between day 12 and day 16 of your cycle. During your period an egg is usually developing, ready for release mid-cycle. The time it takes for an egg to mature within the ovary can vary. This means that the day you ovulate can also vary from cycle to cycle.
