On the pill for a week, condom slipped, but I didnt cum...?

Hey guys,

My girlfriend started taking the pill when her period started last week, and its been 5 days since her period ended.

So we had sex yesterday with a trojan condom that came coated with spermicide, but I didnt cum. When I pulled it out, the condom had slipped off and was inside of her. She got it out a minute later, and shes positive shes not pregnant, but I am a worry wart, so my mind is racing!

Is there much of a chance shes pregnant?

thanks for any help!!
