Trying for pregnancy?

Diamond

Back story I’ve been in a relationship for 5 years now. I was on bc for the first 2.5 years and haven been on it since. We stopped use protection like 8 months in. He uses “pull out” method. When I say he pulls out every time he pulls out EVERY TIME. Fast forward to this past weekend he didn’t pull all the way several times. I was wondering how long of trying did it take to actually get pregnant?
