Hello, I'm having some problems with my period. I'm 14 soon to be 15. 5'1, 107 pounds. Never had intercorse. I have masterbated before, but I usually don't insert things into my vagina. Only once or twice, sorry but I'm just trying to be helpfully specific. I have had my period since September 6, 2012. I mostly use tampons during the day and sleep in pads because they feel awkward and dirty walking around with them.. My period was regular, 4-5 days, once a month, up until last month I had it in the beginning of February then was off for a week then have had it ever since. Its Mostly heavy but once last week i was off it for a day and it was back the next morning. So I still have it. I'm really worried what's happening? Is there anything I can do? It's really annoying to deal with. I'm joining track soon and I don't want to always be dealing with this when I run. Please help. Thank you in advance.
