What are the odds?

Me and my bf were having sex but i got up really suddenly and the condom slipped off and stayed in my vagina, the end was still out and i didnt realize. He didnt keep going once he realize it was off because i got up, and it was just there, at that point we stopped having sex. My boyfriend took it out carefully and said that nothing spilled or leaked, plus he didnt cum and we stopped after that. It was a spermicide condom and it wasnt my "fertile" week. I should be okay right?
