I've heard mixed discussion on this topic so I was wondering if anyone had clarification. I had diarrhea about 50 minutes after taking Yaz. I read online that any diarrhea or vomiting within 2 hours should be considered a missed pill. I called my pharmacist, who told me that only vomiting within half an hour would compromise protection and diarrhea (as long as it wasn't constant, which it wasn't) wouldn't be a problem. Any insight on this one way or the other? I'd rather not take the additional hormones for no reason but at the same time wouldn't want to put myself unknowingly at risk.
