Checking the baby heartbeats tonight (Day 52) on the doppler and they're right on target at 224 BPM (180-240 is normal). I have a pretty good idea of how many pups there are but I'll wait for the x-ray to share.
An x-ray is done around Day 55-57 (next week) to get an idea of how many pups Zene is carrying. Exciting stuff!
