Hey SB, I did a 3 month trial of Cerazette in October. I had awful mood swings, to the point i felt depressed. However, the first month I took it, I had my usual cycle of 27 days, then I had a 14 day period (not much lighter than my contraceptive free ones), then a break of 2 weeks, then another 2 week period.
This went on and on, needless to say I came off it after the 3 month trial. I am pleased I gave it ago, it just didn't suit me.
My GP has put me back on mircogynon (my old pill pre DC) and it is great. However, I won't be able to stay on it for long as I am now 38.
I just stopped Cerazette one day and started taking mircogynon the next, had a bit of spotting, but nothing I couldn't handle.
I would recommend you back to your GP. I guess it also depends on why you are taking cerazette, mine isn't for contraceptive reasons, but because of nightmare heavy peri-menopausal periods.
