Hi, I know plenty of girls who were over 15 when they started their monthly's!....it's perfectly normal up to the age of around 17yrs, I wouldn't think the swimming has anything to do with it, although diet can affect it, when young girls go finicky about what they eat...this can stop periods, I wouldn't worry yourself, we have periods long enough, the later you start the better, we should come with an on/off switch really...switch them on around age 20, and off when we have completed our families!.....good luck

Don't sit up close at the ballet...it spoils the illusion...
