crponies - After I seen your post I had to laugh at myself. Yes, only a horse person would ask a question like I did ( I hope..lol).
Bonnie - I am home now so I will have a little more time. Wow, I can't believe she is so big. I think August foal for sure.
As far as the ultrasound - my vet will usually give them something to relax ( just a little if he has too - he won't if he doesn't have too) - he uses a bunch of gel - he will not ultrasound if he feels it is not safe for the mare. So, try not to be too disappointed if your vet doesn't get as far as he needs too. I have a feeling he will - she seems so far along - I just wanted to give you a little warning. I am with my vet - better safe then sorry! Sometimes the mare is just too small and his hands are too big to do the ultrasound. I sure hope he can for you - maybe you can get some sleep.
I noticed you are watching her at night - that is a great idea - I do the same thing. That way you can see her little changes and it will give you some warning something is up.
As far as the new Vulva picture ( still laughing over that). It looks like it is starting to relax, but it still has some ways to go and it needs to get longer. Of course, this can happen over night also.
