Small baby...please give advice!

I’ve just had a scan, due to me going to the day unit twice in two weeks for reduced feral movement.

The lady said baby boys weighing roughly 1lb 13oz. So he’s measuring small for 26+6.

They can’t determine if it’s due to my placenta not feeding him enough or if he will just be a small baby.

Does anyone remember what they had as a rough estimated baby weight at 26+6? Has anyone had this issue? If so please please give me your feedback and stories.

FTM and very concerned.

I’m also a high risk pregnancy and have never been pregnant before this, no losses, nothing at all.

Also have a anterior not low placenta if that makes any difference!
