Could she be pregnant?

So me and my girlfriend were having . and we kept on checking every 30 seconds to see if the condom ripped. i let out most of my sperm in the shower before she came over. As we were doing it i heard a snap we kept on doing it for about 5 more seconds than i stopped i did not *** inside of her and i had a Spermicidal Lubricant Condoms the trojan ones is there any way she could be pregnant?
