I'm almost 16 and I have been haveing my period for almost 3 years, and y now I thought that they would be a regular cycle, but they arn't. I get my period roughly every 6-8 months and my friends are starting to worry. I was wondering could this be gentic? My mom was the same way she told me when we had that first talk but she hasn't brought it up since then. If you could help me find an answer that would great.
