your menstrual cycle (or period) can last anywhere between three and seven days..
Ovulation occurs at the end of the second week of the Menstruation cycle, which starts as soon as the last period stops, so two weeks after your period stops, a new egg gets released. Sperm can last for about a week in the womb, so you can conceive from about 10 days after the end of the previous period, until about 21 days after.
