For all the pregnant ladies, all the pregnant ladies

Hey, preggo friends!

I wanted to share this super useful chart with you. If you’re like me, then the ultrasound technician’s “Your baby looks good” is far from enough for you.

You need details! How good? What’s good about him/her? Is EVERY PART of my baby is good, or there could be a problem somewhere? (lol)

And if you’re like most pregnant women, you might have wondered what those funky numbers on the ultrasound pictures stand for.

You know, these ones: AC, BPD, FL, AFI, CRL

I’m going to translate it for you and then give you a way to check these measurement against percentiles

AC means abdominal circumference. Basically your baby’s belly. It can indicate growth restrictions, or the opposite gestational diabetes problems and a large baby.
BPD is bi-parietal diameter, which is your baby head size.
FL is femur length, the length of the largest bone in our bodies. It can predict your baby’s height and also possibly show growth restrictions  by comparing it to AC.
AFI is the Amniotic fluid index, and shows how much water you have. A good thing to measure half way through the pregnancy to show any problems, and pretty important towards the end.  A normal AFI amount can also show proper liver function in the baby.  A good number would be around 12, with normal range being between 8-18.
CRL– crown to rump length. This measurement is seen in the beginning of pregnancy, where the baby can’t be measured head to toe.

{I never got around to posting Alexis’s last ultrasound picture. It looks like she’s giving us a finger! Haha!}

So this awesome website I found actually lets you plug those numbers in and give you a percentile that your baby is measuring in, much like what the doctor will give you when you take your baby for its check-ups after birth.

What’s considered normal is a fetus between 10th and 90th percentile.

So here you go: ENJOY THE CALCULATIONS

    When I initially commented I clicked the “Notify me when new comments are added” checkbox and now each time a comment is
    added I get four emails with the same comment.
    Is there any way you can remove people from that service?
    Bless you!
