... I lost one pill (it fell when I was trying to push it out of the pack) so I took the next pill in the set. I have continued taking the pills (never missed a day) but sometimes the order I've taken them in is not always the order that's on the pack (left to right) because I'm one pill short. I'm not sure what to do, I just completed week three of my first pack and then I took one pill from my next pack (for the last day since I was one pill short). I didn't want to stop taking them because I'm sexually active and sometimes i wasn't using condoms. So now I have taken 21 pills and tomorrow I start the seven days of no pills.
