I'm on a 3 month cycle pill, and I take it at the exact same time every day. (10:30pm) can't remember the last time I took it later than that. Anyway, I'm on my second month of pills and I'm having some light bleeding?? The package says this is normal for the first 3 months of taking the pill, but it's almost been a year that I've been taking it?? What does this mean??
