I'm so confused !?

y
So last night me and my SO messed around (I have been off BC for about a month now so I'm waiting for AF. As of right now we're using protection until July)
After we messed around there was some blood as of it was AF kind. Thought maybe it helped it come along .. I had nothing today. And today in the evening we messed around again and there was some , not much. 
If it's not AF then what is it? This has never happened before like that. I've gotten a spot of blood from the roughness but that's about it never more than that. 
I also for the first time off BC did the pull out meathod. Not sure what my chances are with that. We don't want to start trying until July when I'm closer to being out of school.
