No Hedi, we aren't worried, as they can go 69 days and some even 70.
Plus there are signs that we look for that she would be in trouble. She would be at the Vet in a heartbeat if we thought something was wrong. She just really draws things out, she always has.
Every other queen we have is generally right on time.
We're just on pins and needles, cuz one of us is with her throughout.
