Do you have a good chance of getting pregnant if you take your birth control pill every day except on days you have unprotected sex?

Answer 1

To fall pregnant while on the pill you would need to miss a pill (or two) to allow ovulation and then have intercourse. Since sperm can live in your body for up to 3-5 days, having unprotected sex in the days following a missed pill is very bad. I would not say that you have a "good" chance in falling pregnant by missing one pill every now and then. There is a "slight" chance you could fall pregnant. Remember that most pills these days stop pregnancies in TWO ways: Firstly by stopping the egg from being released, and secondly by not allowing it to implant in the uterus. Therefore you are partly protected. To me it sounds like you are deliberately trying to fall pregnant - is this entrapment? It is never a nice thing to do.
