This is my 3rd month on the pill. When I started my period was on a Thursday. Last month my period landed on a Tuesday and I was told that every month, that would be when I got my period. On Friday night I had unprotected sex. I was feeling uneasy about it so I went and took the morning after pill. Two hours went by and I had no vomiting or diarrhea. I took my pill at 4 o'clock the next day as I normally do, but had to start on a new package early because someone had popped out some of my pills on the package I was currently using. That was when I started to get diarrhea. Today is Tuesday and instead of my period coming, I have just been getting discharge. Should I be worried?
