ok this may be tmi but I need to know

I'm on birth control and have been for a few months. my boyfriend and I had unprotected sex about two weeks ago but he pulled out way before he was about to finish. yesterday we had a pretty heated makeout session and he started fingering me. it was a little rough but it didn't hurt. when he pulled his hand out it was covered in blood. we both freaked out bc I'm not supposed to start my period for another week. I immediately went to the bathroom and tried to figure out what was going on. well it looked like legitimate blood. not like menstral blood. it wasn't like I was bleeding profusely or anything. but we stopped anything sexual for the rest of the day. I haven't bled ANY since and when I googled what could be wrong it all had something to do with pregnancy. 
I have a gyno appointment next Thursday and I'll ask him but I need a little clarity before that. 
please no hate because I honestly don't know. I also saw that it could be spotting but I'm not sure.
