What's going on "down there"?

Ok this is really gross but I gotta know. I'm getting a brown colored discharge from my vagina. Idk what it could be because I'm a virgin and the most I've ever done was get fingered. Also I'm on birthcontrol. I missed a few days an then took all the pills in the same day so I'm not sure if that's what this stuff is from. I use vaginal wipes and I wash everyday wish soap. Should I tell someone and go to the doctor or could someone tell me what this is please???
