I haven't read all the replies cos I'm on my phone but pmdd can definitely give you depression and mixed symptoms. My mood charted for the last couple years shows exactly 9 days for me but once the bleeding starts I am fine again. We were in the process of analysing the cycle when I decided to get the mirena which sent me into a mixed state for 7 months, I knew it was related to the mirena but the docs said I was having a severe mixed episode.

I don't remember it being so bad on the pill but I can't take that any more and the mirena was my only bc option. I know I'm safe from pregnancy for another 4 yrs and I have levelled out some now but can still get " bad" the day/ night before I bleed (if I do it is extremely light compared to before).
