My period ended on march 26, and it lasted for four days, and four days is pretty normal for me. Maybe four days after my period ended I got this weird brown/red discharge. It could have been a little bloody but it didn't really look like blood, but I could be wrong considering the red tone in it. The discharge kept coming for a like maybe 4ish days, and then stopped for like 2-3 days and now, yesterday I started bleeding again. Two weeks after my period ended and I'm bleeding again like I have another period. But it can't be my next period. I've had friends tell me that it could just be blood left over from my last period that never came out, but why'd it wait two weeks? 

If anyone can tell me if something's wrong or if I'm totally overreacting, please do! 

Thank you
