I had sex with my boyfriend 2 days before my period, he came in me,am I pregnant?

I had sex with him 2 days before my period, and he came inside me, but when my period came it was like discharge and it was pinkish brown but as the day went on it was a regular heavy period, is there a possibility that I'm pregnant?

It is possible but not likely. Pick up a pregnancy test at the pharmacy and take the test if you want to be sure.
