Pregnant mare/both hid legs stocked up

Question
I live a ways from the vet clinic and it is a Sunday of course.  I have a mare that has been on Regimate Since 4/06.  She is half way through her pregnency and has had wet stool for 2 days.  THis morning upon taking her to turn-out, she is sticked up in both hind legs.  No change in feed or anything else different.  How concerning is this?  Should I take her in?  I can take temp, should have already.  Thank you for your response.

Sincerely.

Answer
ALWAYS A GOOD IDEA TO CHECK TEMPERATURES WHEN SOMETHING AMISS

IF NORMAL, THEN SHE JUST MAY NOT BE GETTING ENOUGH EXERSIZE

IF YOU CAN GET SOME GLAUBER SALTS AT YOUR TACK OR FEED STORE, PUT A SMALL HANDFULL IN HER WATER BUCKET WHEN CHANGING WATER AND IT SHOULD TAKE DOWN THE FILLING IN A COUPLE OF DAYS.
