Well I just had a great appointment with my MFM. It sounds like the doppler he did on me is a bit different than what some of you ladies have had? It was not on the cord, but on my uterine arteries, so not tracking the baby's system at all. It does sound like what he's looking for is the same though, just checking for notching or irregularity. He also did do the doppler on the cord, but mostly focused on the uterine arteries... he said it looked "textbook." I know from what you've all told me this is not a guarantee by any stretch of the imagination, but it does make me happy none the less. Baby was also measuring great, he's in the 54% for size. I'm 22w 1d and he weighs about 1lb 3oz. We will have another u/s in 4 weeks checking his growth.
I'm still terrified.. but it's starting to feel more and more real, that this little boy is my rainbow!
