Need advice quick. PLEASE answer.?

I would say it's very likely. It will be a lovely foal i'm sure. Not all mares are grumpy when they have a foal, and they should be resting for a few months anyway. 1 that was born at our old yard used to trot along behind her mum while she was ridden. If money is a worry you could always keep the foal and put it on loan.
