Ok so i missed Tuesday (pill # 17) and Wednesday (pill # 18) [Which would be in the 3rd week] Had unprotected sex early thursday morning and took the missed pills mid thursday morning. But i threw up about one hour after taking them (Do to hangover). I did take thursdays pill on time though. Im on the pill because i miscarried and am not allowed to get pregnant for 6 months. I should be ok right??
