I'm confused. Are you sayin that when you didn't want to get pregnant, you used the pull out method, and now you have stopped the 'pulling out' ? How long have you been having unprotected sex while trying to conceive?
Getting pregnant is a game of chances, There's no timeframe for how long it should take. Some people take a couple of years. You can always get you and your partner checked out if you've been trying for a long time. Also there's things you can take that help your chances of getting pregant.
