I have been taking the birth control pill Cerazette for about 6 months now without missing a day. The other week I missed taking the pill one day. I resumed taking the pill within 36 hours of the missed pill (i.e. I only missed 1 day, 1 pill). I was abstinent for the next 5 days, while taking the pill, but on the fifth night, I had sex. I then noticed the packet says that after missing a pill, one should use additional contraception for the next seven days of pill taking. I want to know what are the chances I got pregnant by having sex on the fifth day of pill taking, after missing one day (five days earlier) and not using any additional method of contraception. Thank you.

Women can only get pregnant like 5 days out of the month. I would be shocked if you got pregnant under the circumstances you have described.
