Can anyone explain my scan results to me?

Hi,

I don't really understand the measurements part, or the graphs! Can anyone explain?

The graphs show where on the centiles your measurements are. It's a visual representation of the percentage that's shown to the right of the graph.

Sorry, didn't see the second image and thought you meant the little graphs....

Although, the larger graphs are showing the same information too. It's where your measurements are on the centiles.

So centiles are a way to work out how big your baby is. If they lined up 100 babies from the smallest to the biggest tge 50th centre would be right in the middle. Being on the 5th or 95th centile isn't bad persay if everything else is fine, but it can suggest some things. Yours looks fine though I think.

But everything apart from the low lying placenta says its normal I think? Most of those move out the way at your uterus grows. Think if you draw a spot on a baloon then blow it up, it changes position once its fully inflated. They will check again at 32 weeks, best of luck!

Everything with the baby is normal, but your placenta is very close to the place where the baby will need to exit - if the placenta covers the cervix, when the cervix starts to efface, some of the blood vessels can start to bleed significantly and cause problems for you and the baby. It’s called Placenta Previa if the cervix is covered at the end of the pregnancy.

They’re planning to follow up with you at 32/40 to see if its position has changed, which it might do as your baby gets bigger and takes up more space, etc. If the cervix remains partially or completely covered it is certain that you will need to have a c-section.

What is it that you don't understand about the measurements and graphs? Is it the centiles? That just means the percentage of babies that are below that femur (Thighbone) length or head circumference. So 24 percent of babies measured would have smaller head circumference than your baby at that same gestation.

Thank you! Sorry I should've said about the placenta, they made that clear and I've got another scan at 32 weeks.

So we have small head, large stomach and skinny legs?!

Not skinny legs, shorter legs.

Fetal macrosomia can be a sign of gestational diabetes, maternal obesity or excessive maternal weight gain during pregnancy, if none of those apply then they might want to look at some other possibilities.

It could just mean that you’re going to have a big baby.

They have "eatimated" baby size to be in between 5th - 95th centile. That's all. No issues unless they suspect growth has declined or remained stagnant. As long as it is on an upward trajectory and no major fluctuations no need to worry.

DS was 10th and then 9th at the end but was fine.jusg a petite baby.

This is just to compare to what other babies weights are. You will have a similar one once baby is born for height and weight

P.s.having a large baby can be 100% normal. My fit healthy BFF had 4 children all between 9.5 - 10.5lbs she is petite 5'2 weighing 50kg. No health issues at all. She just had big babies.

A week before DS was born my Midwife went to a home delivery of a 12lbs baby. Mother was not presenting with health issues or a large belly. She was fine. Healthy mum and baby. Baby iff the chart and could not be plotted.

Point is don't be scared by all theae numbers it can mean nothing at all rarely an issue.

I think the red markings on the chart are there for baseline reference grid markings of the 5th and 95th centiles - they do not represent OP’s baby.

OP’s babies abdominal circumference is on the 84th centile, with femur length and head circumferences on the 24th and 22nd respectively. So the baby’s abdomen is growing inconsistently with the rest of their body. I didn’t notice that bit when I first looked at it, although all of the anatomical structures covered on the anomaly scan are normal.

It looks like everything’s normal and your baby’s growth is right in the middle of the centiles.

My measurements are similar but I haven’t been given the centiles, everything was flagged as looking perfectly healthy. Try not to worry OP, they would have told you if there was something to worry about.

My DS was born in the 99.6th centile He's measurements were similar to yours at 20 weeks (and with a low lying placenta!) and he was perfectly healthy in every way. Just a mega-baby!

I would take measurements with a pinch of salt from the 20 week scan. Mine were all over the place, small head, very large abdomen and average legs. At the next scan at 28 weeks, it got more proportioned. Measurements aren't 100% accurate and 1mm difference makes a big difference with the percentile. Apart from your low lying placenta (that usually goes up for most eventually), everything looks fine.

Thanks everyone
