Medichi: Pregnant or No - That is the Question!

I went for a ride yesterday in Lake Le-Aqua-Na, and Medichi was acting very peculiar. Some folks riding behind me said "She's acting that way because she's pregnant." I have been thinking ,on and off, that she may be. As I was riding down the trails she was waddling - it felt very strange under saddle. If she is preggers - she should foal anytime between July and late August. That is a pretty large window, but I'm going on the fact that she was in with a black and white paint stud all last summer. I picked her up late last September, from the same field the stud was in. Her abdomen is extended quite a bit. I'll be keeping a very close eye on her, and I'll keep everyone updated on her progress.
