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.
Every female is different, thus every period is different. 28 days is the average but it could range from 21 days to 40 some. you can always expect your period 14 days after you ovulate. you may not receive your period every month since exercise, weight, and age may also affect it. Most women get their period for about one week out of every month. you should get you period every 28 days.
