Hi Gigglebabe
I've always had a problem with this too, so much so that I was totally out of action for that week, so I started taking the pill without taking the sugar tablets- just skipping them so I didn't get a period. Perfect!
But now after having Hannah almost two years ago (who can believe she's almost two!?

) I've been having 14-27 day periods, with only a few days break before they start again. It's been driving me nuts! I tried going back on the pill but now it doesn't make any difference.
I've also had the hysteroscopy, d&c and biopsy with no great findings. If my rsd didn't get worse when I'm like this I could probably put up with it more, but I just can't keep going like this all the time, its exhausting and so disabling.
Anyway, I hope they can find some way to help you. We don't need more flareup triggers, hey?!
