Hmm, I notice the OP won't answer the question about the vet check? What is with horse owners who do not want to spend the money to have the vet out but want to know when their mare is due, IF she is due, if her stomach makes her look pregnant, when she will foal and wants to know by the photos they send?
My older gelding always looked pregnant....... ALWAYS ... Didn't need the vet to tell me he wasn't.
But, with mares, I am amazed at how many folks won't spend the money to have a vet check, but get online and act all worried and wondering what to do. Get the vet out, have the vet check and A: find out if the mare is even pregnant B: get a clue as to how baby is positioned, and C: do an ultrasound to find out a gestimate of when foaling might occur.
