Post-MS Anyone?

I am thrilled that AF arrived, but I found myself in a bit of an emotional slump today. I wracked my brain to figure out what was wrong with me and then it dawned on me that I hadn't had many periods this year given all the IVF attempts we'd undergone. I'd forgotten, literally forgotten, that I'm one of those rare birds that doesn't get PMS (as in pre-menstrual syndrome), but I instead go through a bit of a Post-MS of sorts.

Many women find themselves feeling cranky, bitchy, desperate to eat chocolate *before* their periods. Not me. Mine screwed-up hormones kick in afterwards. In this case, CD3. I find myself depressed, sad, weepy, just plain miserable. I don't fly into rages, but find myself feeling more withdrawn and sullen. I don't understand why this is. One friend, a nurse, said that maybe I'm having a sort of negative feedback reaction to the increasing hormones at the start of AF. Hmm, maybe.

I haven't met anyone like this. Anyone else as whacked-out as me out there?
