How much of a chance does my girlfriend have of being pregnant if using the pull out method, we also just had a son 1 month ago.

Moderate : Withdrawal or the "pull out" method is not birth control! don't fool yourself or your partner - use a condom or some other method of contraception. There can be sperm the the fluid released from the penis during intercourse before you ejaculate and she can get pregnant. Most doctors recommend not having intercourse for 6 weeks after a baby -while not common it is very possible to get pregnant!

Too much: Withdrawal is a very poor method of contraception. Unless you want another child you and your girlfriend need to get serious about this and get help to make real plans to avoid another pregnancy.

Is possible: Pull out or withdraw still puts out a drop of semen with sperm that is enough to get a woman pregnant. If she is breast feeding full time she is less fertile. Having just had a baby a month ago it is really important for you and your girlfriend to use a reliable method of birth control for at least a year. Two pregnancies close together is not healthy for mom or baby.
