It seems like our bodies have it in for us, doesn't it?!
Mine started up exactly ONE day after my doctor said, "Well, looks like your periods won't ever be coming back." I'm sure those words must have triggered some secret internal body alarm...."ooh, quick, she's feeling good, can't have that!"
I hope it is just a "stress" event and doesn't repeat. (After all my work going around and getting opinions from 3 doctors about having the ooph surgery, turns out my insurance company says "NO"...they consider it medically unneccesary...I consider them...well, you just can'y type that here on the board!)
Hope things look up soon!
