pull out method??

So I've been using the pull out method with my bf for 2 years now and we have never had an "accident". We've been having sex frequently and I am 8 days late, I've never been this late before. He's never came inside of me, should I get a pregnancy test or just wait it out?
UPDATE: I forgot to mention that I am allergic to latex, and am not able to get birth control without mom finding out. I am under 18
