Help, worried about pregnancy?

I had sex (with a condom) and he didn't come inside me and pulled out and the condom didn't break (I checked it after). Also I was on the last day of my period so there was only a little blood. But I haven't been feeling well lately and I feel like I'm having cramps. But I'm about to start ovulating and apparently you can get cramps from that. I'm just really really really worried bc I think I'm showing symptoms of pregnancy even though it's highly unlikely. I'm really scared. Any advice?
