Did you have a less-than expected fundal height?

My usual OB canceled for my 28 week appointment yesterday, so I met with a different doctor who was a bit brisk and awkward (he gave me an unsolicited lecture on weight loss after the baby even though I am not overweight and have only gained 16 lbs, so definitely nothing excess). He was nice and meant well (just an old guy) but I was uncomfortable and didn’t end up asking any questions so here I am on Reddit. My fundus measured at 26 weeks which he said was normal if you’re petite (I’m 5’6 so not really petite by my understanding) and everything has been going smoothly so he wasn’t worried. Assuming nothing is wrong, does this mean my baby is smaller than average? She measured 50th percentile for everything at the 20 week scan, but my husband was born tiny (<6lbs full term) so maybe she will be smaller too. Wondering what experience you all have had!
