Ten days before period? Pregnant or just Pms?

Should I be worried?

I took a test yesterday and it was negative. I am a little scared because I had unprotected sex with my bf a week ago, three times I think but everytime I gave him a blowjob and he came in my mouth.

I've read also that sports could cause sore boobs (I did for the first time on sunday a dance choregraphy with cardio and aerobic) and that was the time when my boobs started to hurt.

What do you think?
