Can my girlfriend get pregnant in this situation?

Im a big worry wart and i wanted to know if my girlfriend could have gotten my pre- on her hands by touching my then putting on a trojan-enz spermicidal lubricant condom. i didnt know if the pre-*** could have transferred on her hand and then onto the end of the condom. also today is the 30th day of her cycle and she hasnt gotten her period yet. I just wanna know what u guys think
