50/50
the probability is very small
If you take your pill everyday without missing any pills you are 99.5% protected from getting pregnant, but the pill has no protection from STI's.
There is no known percentage for definate. if you use a condom then there is roughly a 5% change of getting pregnant, where as if you use no protection or contraception, the risk is considerably high. if you dont want to become pregnant you may want to consider birth control, and also without a condom you run the risk or catching an STI or STD.
Birth control pills Don't have sex Diaphragm
of course. the birth control pill is very effective if taken correctly. there is always room for human error, so yes there is a chance of getting pregnant while being on birth control and no condom use.
20 percent without condom
If you have sex without using some kind of birth control, then you'll get pregnant. It doesn't happen EVERY time, but if you continue to have sex without using some form of birth control, you WILL get pregnant. Use a condom. Every time, until you WANT to get pregnant.
