Breech baby with small head

[Piglet11]

At my 20 week scan one of my babies (I’m having twins) was measuring on the 50th centile for head measurement and at the time was head down. I had a growth scan yesterday (at 24 weeks) and the same baby is now breech and is on the 3rd centile for head circumference. I was so worried about it but the consultant said it could maybe be to do with the baby being breech and not able to get an accurate measurement. Has anyone has this and everything been ok. I’m having another scan in 2 weeks to see if there is any change but meanwhile I am terrified

It seems a big difference in just 4 weeks, must be a mistake. Did they tell you that at the scan because they shouldn't be recording if they couldn't get an accurate measurement? Or give your consultants secretary a call on Monday and leave a message for him/her, I'm sure they would of booked you in immediately if they were concerned.

When's your next scan due?

They took ages to get a measurement as they said baby was moving a lot. It was only after the scan that a consultant told me a possible reason for the result was because it was breech. I am leaning towards the results just being faulty as I’m too worried to think that it could actually be real
