Obese, Anterior Placenta & Small Baby

Hi

Im currently 23 weeks but have been obese since before conception and at my last ultra sound was told I have an anterior placenta all of which might mean I won’t feel baby for a while according to what I’ve read.

To top it off I was told baby boy is two weeks behind in size but so far tests have come back negative.

I’ve felt flutters for a few weeks now but no major kicks or movements.

Is it too soon for me to expect to feel this? When do you think it’ll happen?

Any suggestions on how I can help baby grow?

Any general words of wisdom or encourage?

Thanks :)
