Miscarriage?

I have no clue if I was pregnant or not. Last night I got drunk with a friend and came home to my boyfriend. We had sex, when I woke up this morning there was blood everywhere. I'm not sure if it was there last night because it was dark and I was obviously drunk and tired. I've been having period like cramps all day today, the blood continued a little bit, I know it wasn't period blood. No clumps, no clots, just sort of spotting. I know I need to take a pregnancy test, I'm going to do that asap. Just thought I'd get some opinions. If it were a pregnancy/miscarriage, it was early, because I had my period last month. Thanks!
