I just bought a valuable broodmare that was supposed to be open, but was scanned last week and would have a 30-32 mm embryo according to the vet report. I will have another ultrasound done soon to make sure it isn't a cyst, although the vet was pretty sure it's an embryo. I would need to have an idea of the "age" of that embryo, so I can figure out when/where she was bred.

She could have been bred on the seller's farm, or on one of the layover farms during transport (she crossed the whole country). Knowing when she was bred would be the only way to know where it happened, as everyone implied says she wasn't bred under their care.

Also, if she is indeed in foal to an unknown stallion, is there any way I could have this pregnancy safely stopped to rebreed her? As stated, she is a valuable Warmblood mare, and I do not want to put an undesired, unregisterable foal on the ground. I heard that aborting a mare often leads to no other pregnancy before the next breeding season...

Any help welcome!
Thanks!

An embryo that size should be about 30 days old. Prostin shots (3 days in a row) should lyse the CL and terminate the pregnancy. Prostin stops working as well after about day 38-40, when the endometrial cups form. Thats why it's hard to bring a mare back around after that time period. Time is of the essence since you are pretty close to that timeline.
