Does anyone know what chances are of getting pregnant if you're using a condom and you're on birth control are?
With hormonal birth control alone, the chances are less then 1%.
Very very slim to none. Birth control alone is 99% effective when used correctly, add condoms to that and if you get pregnant then it was certainly a "meant to be" kid! I never want to say never but it would be a very very slim chance if you were taking birth control correctly and using a condom correctly. Birth control pill failures usually happen when women miss pills or are on antibiotics without using back up. Condom alone failures usually happen when either people try slipping the penis in for a "few strokes" without the condom and expose themselves to sperm that way (sperm are leaked out all through the sex act not just during ejaculation) or the condom breaks. Using birth control pills and condoms together would really make it virtually impossible but again, I never want to say never but chances would be slim to none.
DON'T trust when people say that birth control is 99% effective because it ISN'T. It can differ for everyone, especially since some people aren't 100% consistent at taking it every day at the exact same time. According to the CDC, birth control has a fail rate of 9% and condoms have a fail rate of 18%. So that leaves you with a fail rate of probably around 2% if you combine them, so thats pretty safe.
