Hello, i am no longer on the pill, had unprotected sex, he didn't pull out yesterday. what are the chances of pregnancy and is there a way i can prevent it now?

Depends: The chance of a pregnancy with unprotected intercourse depends on where you are in your cycle. However you can use Plan B One Step over the counter and that will prevent 7 of 8 potential pregnancies if taken within 72 hours of intercourse. This is not a good choice to use as your regular method of contraception so you may consider your alternative options. Hope this helps.
