I thought that I was having a period but 2 weeks later I'm still bleeding. I've phoned the doctor and they said to put up with it for another 2 weeks then go back! I work away so was on my period when I left home and will be going back still on period. I'm not sure why I was put on cerazette, was recently diagnosed pre menopausalI can't get pregnant, don't ovulate. My migraines have disappeared, was having at least 3 a week.SeX drive gone out the windows and apetite gone. Im not hungry when on a period a lot of pros and cons! I might just stop taking it, what's the worst that can happen
