Spotting or period?

So, this weekend my boyfriend and I had sex twice. The first time around, I started bleeding slightly but I thought it’s because my boyfriend and I hadn’t had sex in awhile so I didn’t think it was a big deal. Second time around, I started bleeding again, to the point where I’m wearing light pads. I don’t know what’s going on? I just had my period literally two weeks ago so I don’t think I should be having my period again? I’ve never had this happen to me before.
