Hi,
Unless she's continuously vomiting, I don't think the ER vet is necessary but definitely a call or visit again to the regular vet. It's true that some puppies will vomit with some regularity. The yellowish, foamy, frothy substance is bile. This can happen when their tummy is empty and gastric juices aggravate her GI system. For that, my vet had suggested giving a small portion of the days kcal/feeding portion shortly before bedtime.
How many meals a day are you giving her and when each day? I haven't read the hypoglycemia sticky thread in a while and I don't think this is the case, assuming your vet went over that with you, but it's worth looking thru that. If the food is what the breeder was feeding, then it's not likely to be the cause. If her food was changed not long before this started, or if it was changed but not transitioned slowly, that might be a factor.
The reassuring things are that she's otherwise acting normally.
