Parmela, for what it's worth, several of ourvmares have tested ready for weeks. Many mares on Mare Stare have tested ready and waxed for weeks this year. It may be something in the air with these solar flares. I think it's Gods way of showing us that it's ultimately in his hands and she will go when she is ready and not a moment before.
Unlike Wishy, she doesn't seem miserable, she is very perky, especially at cookie time. She really is happier inside as well. She had the door open yesterday and spent sometime out, but a lot of time in.
They say a "watched pot never boils", but sooner or later she will foal, and she isn't overdue yet.
Breathe.....and relax.
