HELP LATE PERIOD

Kate

Okay so I'm 6 days late for my period and yesterday and today I got this brown watery almost discharge. This happened to me about a week ago too and lasted for a few days. Can someone tell me if it's my period or if it's happened to you too because I'm 15 and not a virgin.. Last time I had sex was 37 days ago but we used a condom and he pulled out too. I've had no symptoms of pregnancy
