Hi I Was On Microgynon For Many Years And Then

Hi I was on Microgynon for many years and then noticed that it had been changed to rigevidon, I have since put on a stone and half and noticed that I have been having bad mood swings, so a few month ago I stopped taking them, I have noticed a considerable difference in my mood, I do not suffer from bad moods now. I went back to the doctors and asked for Microgynon and was told that it wasnt down to the pill because they are both exactly the same. As I am 38 she had put me on Cerelle which I have heard alot of bad things about, to the point that I am not going to start taking it. Are you aware of any difference to the 2 pills Rigevidon and Microgynon? i really want to go back on the Micro and just see how I go from there, my blood pressure was absolutley fine.
