Scared?

Kayla
Ok, so I'm not late (due in ten days)  or having symptoms... But my BF is terrified of pregnancy, we had sex on day 1 of the fertile cycle.  He used a condom, pulled out, and checked for leaks after.  It never slipped off or burst either.  Idk what to tell him, he gets so tense after sex.  Does he have a right to be nervous, could I be pregnant?
