Pregnancy Ultrasound #15

At 36 weeks, 5 days we had the 36-week routine ultrasound through the radiology department. The ultrasound tech either a.) didn’t speak much English, b.) was extremely precise and got exact measurements, or c.) wasn’t sure what she was doing and/or was nervous. I could be convinced of (a), but based on seeing a friend’s newborn twins who weighed one ounce apart at birth yet were measuring a whole pound apart just a week before through the same medical provider, I’m going to guess it probably wasn’t (b). Hence, I don’t have a whole lot of faith in the measurements we got at the ultrasound, but if they are even remotely correct, at least they do show that things are moving in the right direction (ie. growth). We did get a boatload of photos, only two of which are not creepy hollow-eyed images:

Baby A:

Baby B:

Today’s measurements:

Baby A

  • Heart rate: 123 beats/min
  • Biparietal diameter: 8.92 cm
  • Head circumference: 31.51 cm
  • Abdominal circumference: 31.85 cm
  • Femur length: 6.99 cm
  • Estimated weight: 6 lbs. 3 oz.

Baby B

  • Heart rate: 129 beats/min
  • Biparietal diameter: 8.46 cm
  • Head circumference: 31.24 cm
  • Abdominal circumference: 30.97 cm
  • Femur length: 6.75 cm
  • Estimated weight: 5 lbs. 8 oz.

So far, Baby A is sticking to hir guns and is still breech; Baby B is still head-down but appears to be (so far) losing the race to exit first. Baby A’s measurements correspond to a gestational age of 36 weeks, 1 day and Baby B’s measurements correspond to a gestational age of 34 weeks, 5 days. We’ve been told that a difference of two weeks between the twins is normal, but because Baby B has an estimated delivery date that is 13 days different than the original due date, our doctor said he is having a perinatologist check it over. We’ll see what they conclude at next week’s appointment about their growth and position.

Molly’s cervix also measured 3.3 cm (compared to 3.73 cm four weeks ago), yet the OB said at our appointment last week that she was 50% effaced. More reason to doubt the entire ultrasound measurement process. Anyway, I assume this will be our last routine ultrasound, unless they have something to be concerned about from this one in which case we’ll likely have another.

Seeing our friend’s newborn twins – who were born at 38 weeks and are freaking adorable – really put everything into perspective. That’s going to be us so so soon!
