I'm 21 years old. My menatrual cycle is VERY random and I'm never on time, sometimes I skip a month or two and it is very common since as long as I've had it (at 11 years old) I hadn't had my period since the end of march and on the 2nd of July I started what I believe is my period. It's almost like a discharge, brownish color sometimes but mostly just blood. I never usually have that and it's already been 2 weeks with it while it usually lasts about 5-6 days. My fiancÚ and I have not used any kind of protection but him pulling out where I know we've had some close encounters. I don't know if I might be pregnant or maybe had a miscarriage, or if my period is just being weird. Help!
