We just got home from our in-depth follow-up ultrasound and I'm very happy to report that everything looks completely normal! The two 'soft markers' that the original ultrasound tech found have basically disappeared, praise the Lord! The Perinatologist also remeasured pretty much everything and it all looks good. She was quick to remind us 50% of Down Syndrome cases go undiagnosed from ultrasounds alone but from the looks of it our LO is perfectly healthy.
Thanks so much for the T&Ps!
