Anyone else get this at certain points in their cycle? I'm due AF some time between yesterday and Thursday, and I've had horrendous restless legs the last couple of nights and my knees are sore when I exercise. I'm thinking it could be a hormone thing linked to progesterone, it (well, the knee pain anyway) happened when I was pg, and it's been happening since just after ovulation. Anyone know anything about this? Just curious - seems weird!
