First of all :wave: A big welcome here.fcnubian said:!
The vet can do a ultrasound (I think is what they are called) and see if she's bred.
If she is, it would probably be best to lute her now instead of waiting till kidding time, And then the kids end up being to large. I would rather lute now and not have to have a c-section.
Thats just what I'd do.
