Hmm.. No, I doubt that you made a mistake if you had the calander in front of you. Are you going to have the vet out?
I have a call in now to the vet. She will call back sometime today. If she thinks the mare needs to be checked again, I'll take her in.
I did just read on a site that some mares don't bag till a few days before delivering. I just can't fine where they will be several weeks out bagging one time and days out the next.
