i thought i had started my period today, like a really heavy flow. it was up my thighs and all over my vagina and on my pyjama boxers too.. so i cleaned myself up, and put a pad on and thought it was okay.. but it keeps on bleeding? i masturbate with a shower head quite often and with my finger and im scared that could have done something bad.. when i checked the blood was brownish and dark but since i put the pad on and it's still been bleeding it's more of a brighter red... by the way im 13 if that means anything.... whats happening?
