What does it mean when I'm having my period every 2 weeks?
I'm 14 and I've been having periods since I was 11 and the first year wasn't regular(which is pretty normal) but I've been regular ever since up until last month. Normally, I would have my period for 7 days and around 28 days off. This is the third time in a row that I've had it for 7 days and only 15 days off. I feel so exhausted now and don't believe this is normal. Any explainations or advice?
