Please answer I was having intercourse with my gf and had a spermicidal Trojan on the whole time I did not eja?

Vulate inside her I pulled out she was a virgen also. The condom did have precum and it was about 3 days after her period what's the chances of the pre *** escaping? Also I did # 1 about 3 hours before this happend should I worry? Or not really I checked the condom after wards no hole I even filled it with water and nothing dripped and I saw the sperm in the condom when I finished but my conscious is messing with me
