7 days late after sex with condom

I'm severely panicking because I had sex 4 days before my period was due and we used a spermicide condom and he even still pulled out, but I still haven't gotten it 7 days past the due date. I've had some very light cramps and my breasts were only sore for a day. The condom didn't break, so could I actually be pregnant? I don't know if my constant severe stress over it has anything to do with pushing it back more. My period is usually very regular and that's why I'm so worried.
