Here's the official data from Planned Parenthood: * Of every 100 women whose partners use withdrawal, 4 will become pregnant each year if they always do it correctly. * Of every 100 women whose partners use withdrawal, 27 will become pregnant each year if they don't always do it correctly.So if you did it correctly as you say, you have an effectiveness rating that's comparable to the pill (96% versus 97%)A lot of people are going to tell you that you're dumb for using this method, but that's not necessarily true. What do you think people did before the invention of condoms? The reason that the pull-out method fails so much is because it's usually employed by teenagers, young people who can't get or can't afford other forms of birth control. That's a big problem, because teenagers just don't have the sexual experience to know when to pull out or not. Also, it offers zero protection from STD's. If you're going to use this method as your primary form of birth control, continue to do it correctly or your chances of lucking out drop to 73%. Not so nice, right? As for this time, I'd say you're probably okay.
