I'm on femodette and have been for about 6 months. I was on it pre dc's and it was fine so went back to it afterwards.
However I don't think it's doing me any favours. I get very tearful a week before AF is due, angry, upset easily, short temper and craving carbs like mad (which is not ideal for my ibs). Then when my period starts/ the day before I get a really bad headache which doesn't shift easily.
The PMT is making me really hard to live with and add the headaches to that and I'm a miserable cow for 1 week out of every 4. :(
I'm going to go back to the dr. I'm guessing they'll either suggest a different type of pill or having a coil - which scares me a bit 
Any thoughts/ advice?
