Worried about 20 week scan measurements - are these okay?

[lostandconfused2]

I'm a first time mum and this is my first pregnancy. I'm 19+6 today and I had my 20 week scan. I was told everything looked normal and baby is measuring on time but I'm a little worried about the measurements as a couple of them are way below the middle line on the charts.

Can someone tell me if these are okay? I worry about everything.

HC: 179.8 mm - 80%

Vp: 7.4 mm

TCD: 18.5 mm - 12%

CM: 4.5 mm

Nuchal fold: 3.3 mm

AC: 140 mm 32%

Femur length: 34.5 mm

Fetal weight: 12 oz.

The TCV and AC is lower? Anything to worry about?

Thank you.

Anyone?

Don't worry they definitely would have told you if anything was wrong. Those scans are very unreliable too, and also all babies grow in different ways. I had serial scans for my second child and his head measurement was very near the bottom in every scan, it didn't mean anything (and his head is normal!).

No, nothing to worry about. All babies have variation and only 1/100 will be on the centre line (and not even for every measurement).

It's also easy to measure 'off' by a fraction of a mm which will hugely affect the %s. Babies are still quite small at that stage...

Thank you both! I can rest easy tonight. I'm high risk and everything is a worry for me. Praying he continues to do well.
