Is it microgynon? I took that for all of about 6 months when I was first married, and my poor dh didn't know his new wife. Things improved no end when I stopped taking it.
I've tried another combined pill (Celeste, I think), and the mini-pill, but I just don't really seem to get on with them. I was having Depo injections; I think I had 3 or 4, and I think it was a contributory factor in me needing anti-depressants. (There was a lot of other stuff happening for me - I don't think the pill would do that all by itself!)
