i'm 18 and i got my period when i was 10. it was normal for the first 5 years but it started becoming irregular and now it comes every 2 and 1/2 months or so. i'm wondering if something is wrong with me or is this normal. i experience period like symptoms every month though (cramping, mood swings, insomnia and swollen boobs). i also have like heavy white discharge for a few days every month.
