12w4d - NT Scan

Today was our NT scan and I don't think I've ever enjoyed an ultrasound more. Little bean was much less bean and much more tiny, wiggly, stubborn person, I couldn't stop smiling and laughing watching them. I was holding my breath when the tech first put the wand on my belly but before I could ask if baby was okay and had a heartbeat, they started waving their arms around and squirming. They wiggled left, then right, arched their back and squirmed all around. It was beautiful.

Turning on their side, wiggling their little arms

We saw them swallowing big gulps of amniotic fluid and begin to suck their thumb. We got a peak at their brain, which is developing perfectly, and when we went to check out bean's organs, we caught them practice peeing! Their little bladder was full of amniotic fluid and they just happened to empty it right then. It was incredible to see them moving and dancing so much when they're still too small for me to feel. I can't wait to feel some of the acrobatics going on in there.

Baby on their side, showing off their tush

The whole point of this ultrasound was to perform an NT scan, a nuchal translucency scan. The NT scan measures the fluid in the tissue at the back of baby's neck to look for markers of chromosomal abnormalities. Babies with chromosomal problems often accumulate a build up of fluid in their neck which results in a larger fluid space and a bigger measurement.  To get a clear reading, the tech needed baby to look up so we could get good measurements of the back of their neck. It seems simple enough but little bean clearly had other ideas. Every time the tech got close to the right shot, baby would roll over onto their side and give the tech their butt. The tech would ask me to cough, which makes baby jump, but bean would just wiggle and squirm and show off their tush again and then I'd laugh which also makes baby jump.

Eventually we were able to get a couple shots and baby's fluid is measuring a perfectly normal 1.3mm. Amazingly, although I'm only 12w4d today, baby is in the middle of a growth spurt and measured an impressive 7.08 cm which correlates to 13w2d! Clearly they're still an over achiever. Their heartbeat was also perfectly on track, 156 bpm. I wonder if this growth spurt is why my morning sickness came back, although they were measuring perfectly on target at my last appointment which was the day I started throwing up again.

Our next peak at baby won't be until the end of July, another long stretch without getting to see our little bean. They already look like such a perfect little person now, I can't wait to see how they've grown at 16 weeks. If anything funny shows up in my blood tests, they'll call at the end of this week but since we added on PGS and know baby has normal chromosomes, I don't anticipate any problems. Baby just needs to keep doing what they're doing and grow, grow, grow.
