Could my girlfriend be pregnant?

So 2 days ago me and my lady had . I used a trojan-enz lubricated condom. After about 2 minutes of I checked the condom. On the outside was this white material. I immediately pulled out and stopped. I didn't *** or anything. Could this be just the lubricant from the condom? There weren't any holes in it either. Please help me, I would GREATLY appreciate it.
