Ok, I know this is a tough question, but I have a dilema in not knowing if my mare is overdue or has a few more weeks. Her size makes me think she is now overdue. Here are her ultrasound pictures from last September. Can anyone just give me a guess as to how far along she was in her pregnancy when they were taken? I have two definate breeding dates, but don't want to say them yet, so I don't sway someone's opinion. Thanks!
