What are the chances of pregnancy while using the "pull-out method" and having sex daily? (partner pulls out about two seconds before ejaculating)

Not a good method. The chances of pregnancy are high with this method. Please see your doctor and get another form of birth control. Condoms should also be used for further protection against pregnancy and infection.
Not great but. In the literature the rates of failure for the "pull out method" or coitus interruptus are around 20%! Remember this also doesn't protect your against STDs, so reconsider using a barrier form of birth control if you really want to be safe.
