Try not to worry (I know it's impossible!!)

My tummy always measured smaller and was told all these possible worst case scenarios by my dr. I had to have a scan at 37.5 w and it turns out he was fine.

As it was my waters broke 2 days later and he was born right on 38w measuring 46cm and only 5lb 14 (2.67kg) The u/s said he was over 3kg so they didn't even get that right!

Anyway, he was perfectly healthy just a small little boy. He's still quite short for his age but he's probably going to just be little like me!

I don't know why they go on so much about all of that, it really irritates me as you get so scared that something is wrong. I'd like to know the % of people who's babies don't grow in their tummies properly at that stage!!!

Good luck with your scan - let us know how you go!
