x2I'd certainly check her temp.
Many years ago I knew some folks who had a wreck on the way to a goat show - they were rear ended and one of their does came off the trailer with a bloody vaginal discharge. Show vet gloved up and did a quick vaginal sweep and came up with no real answers. His advice - wait and see. UGH. But, there really wasn't any other choice BUT to wait and see...doe ended up being fine and delivered healthy kids several months later. But, they might have just gotten lucky.
Couple things running through my head...
Has she ever kidded? The uterus can keep a low grade infection going for a long time with no other symptoms.
Common belief is that goats do NOT have a bloody discharge during heat - but I guess there could be the odd one that does...
Just tossing some things out there. Hopefully since your gal 'seems' to be ok - I hope she truly is!
