My mare didn't pass the pregnancy test...or did she?

Have you ever wondered if your mare was pregnant?  In the old days I would have just called the vet and had him come out.  If he charged me $150 to tell me a big fat 'No"; I wouldn't be very disappointed.  In the new days I just can't do that.  The other day I was waiting in line at the dollar store and much to my surprise there were pregnancy tests for $1:00.  $1:00 was worth the experiment. Below are the results.  My mare would be 8 months at the time of the test if pregnant.  Well, she didn't pass.  Still, I will keep and eye on here.
