Yeah I agree with whats been said- and if the vet doing a quick once over on her said that it is possible then it is definitely worth it to get an actual yes or no answer- because she is extremely round and the added pic of her does look like she's bagging up.. its really hard to tell with ponies though because they can put on a lot of weight quite easily and look pregnant.
Do you have any guess on how old she is?
