The chances are slim?

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 because the condom end was still hanging out my vagina. Plus he didnt cum and we stopped after that. It was a spermicide condom and it wasnt my "fertile" week. I shouldn't get pregnant right? Ive had sex with condoms before and havent had any accidents or gotten pregnant from it. But since the condom wasnt "lost"in my vagina and he didnt even cum at all and i wasn't fertile and it contained spermicide i should be fine right. Im a bit overweight and havent gotten pregnant at all, and my body isnt in the right health to carry a baby, i should be good?
