Was I drugged or did I black out from alcohol?

I was at a overage club with some friends and before I got there I had about 2 coolers, a martini and a shot of jack. After that I remember having 2 shots of vodka at the club. Right before taking my second shot at the club, this guy was talking to me about how he used to roofie girls right after I took the shot. After that I don't really remember much and the guy was apparantly unhooking my bra a couple times but my friends had saved me. I really blacked out most of the night except certain parts. I don't even know how I woke up in my bed the next day. Please help!! :(
