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.
First off, if you dont want to get pregnant then no matter what dont have unprotected sex. A condom is alot cheaper than a baby! Also, normally you are not fertile right when you get off your period. If you have a normal cycle, you should ovulate 14 days after the first day of your last period. Every woman is different though and ovulate at different times, so there is always a chance. Remember though sperm can live inside you and wait till you ovulate anywhere from 3-7 days. Use protection!
