Bleeding a lot but not even close to my period

So last night I masterbated which isn't unusual, I thought I was just wet. I woke up and looked at a rag I used to wipe off what I used. I saw it and it was completely bloody. I thought I might have had my period but I'm literally 2 weeks away from my period. Bleeding a bit is normal for me especially if I haven't done anything in a while but this was a LOT of blood. I'm kinda worried. Any ideas?
