Is it possible for you to get pregnant while having food poisoning during unprotected sex?
Yes, you can get pregnant any time you have unprotected sex. It might not be the most pleasant experience to have sex while you are experiencing food poisoning with vomiting and diarrhea. In the case of the scenario: you had intercourse, then took your oral contraceptives at the regular time, but, vomited within a few hours of taking your pills. In that case, you may not be fully protected and you do need to use condoms. If this happened, you may want to consider Plan B, taken within 120 hours of unprotected intercourse. The sooner you take Plan B, the more effective it is.
