Nope, I don't know anyone that got pregnant from the pull out as long as they actually kept on pulling out. DF and I made the mistake of not pulling out during times when we didn't think I was fertile because I kept very close track of my cycles and we got pregnant from that. The key to the pull out method is consistency, always use it even when you don't think that you'll need it (unless of course you're trying to get pregnant). Condoms never hurt either.
