I have been taking mononessa for a year. I am not currently sexually active and haven't been for quite a while but have continued taking it just in case I do become involved with someone. Anyway, I was supposed to start my period on May 10, but had a Pap smear scheduled for the 12th. I did not take any of my green pills so that I would not be bleeding for my appointment. So I started my next pack after I took the last blue pill of my last pack. Today I started spotting, which has never happened at all before. Is this normal, and is this a possible period? About how long will I spot? I am on the 12th blue pill in my current pack.
