Growth scans

Kayleigh

So I had a growth scan at 28 weeks and they told me I was measuring at 31 weeks... they sent me for a scan and everything looks fine and baby was fine. Iv just had my 32 week appointment and baby hasn't grown so I have went from the 90th centile down to the 50th 🤔 has anyone had anything similar and should I be worried? Baby is very active so no worry about movements
