This kind of a funny question, but my mare may have been bred over a fence. She would be six months along, and she is showing. I don't know if she is getting fat, or pregnant. But she is really sensitive in the hind end, and her belly is like a pregnant horses belly. So to get to the point, Can I buy a pregnancy test from the store? Will it work on a horse, and have you ever used one! I am putting some pictures up you you know what she looks like!
