So sad, we are almost at 6 months and no progress. Had 5 month shot and dr said if she isn't showing this next month, she will do another manual check. I think she re-absorbed. :(
Oh dear. I hope this is not the case. Just know that horses don't 're-absorb'. If they were pregnant at all, they actually lose the fetus as they would in an abortion, although it would likely be too small to notice.
