And even if you did know her well, as with women, there are indications of likelihood, but the only way to be certain is to do a pregnancy test. Call your (*good* equine)vet. I say find a good equine one, because there are other concerns if she is pregnant, that you may need to learn about, such as ensuring good(but not too much) diet & nutrition for the mare, keeping her exercised & fit(fit, healthy mares are less likely to produce foals that are born already lami-prone) and the multitude of other stuff you may need to learn/do to prepare for a foal.
