During the 2nd day of my 3rd week of my pill pack (I take Yasmin), I took my pill at my normal 8 am time. Later that day, starting around 3 pm, I had diarrhea pretty bad and was in and out of the bathroom. A few hours later I also started vomiting and having diarrhea at the same time. By about 10 pm or so, I had gotten some probiotics from the doctor which really helped. I didn't think to ask about the pill because at the time I hadn't had sex in over a week. The next day I just continued taking my pill as normal and skipped my pill-free break. I didn't double up at the time because I would have run out of my pills before I could get a refill, as I was out of town. About 5 days later, I had unprotected sex with my boyfriend. I was pretty nervous the next day, so I took plan B about 27 hours after the incident. I know that missing one pill with my pill usually isn't a big deal as long as I make it up, but I didn't at the time. How much would this affect my chances of getting pregnant? I can't stop thinking about whether or not I may have ovulated after possibly not absorbing my pill and not doubling up.
