So my mare is maiden and is 345 days pregnant, she had showed signs of labor about a week ago, and I think she lost her mucous plug, and now she has lost her bag and isn't showing any signs. The area around her tail is super soft like jello-y, her stomach isn't huge and it seems normal, but it seems to have dropped some. Her back bone is more prominent and her ribs are starting to show when she breathes in, (I've never been able to see either). So my question is how long do you think she has? Disclaimer- I am 100% positive she is pregnant! And I know she hasn't aborted!
