Baby small on growth scan?

Alissa • Dear son born 5/7/18. Three angel babies. Dear son born 8/27/20 and pregnant with our first girl and last baby Pittsburgh PA-C

I had a growth US at 27w +2 days and baby approximately weighs 2lb and 4 Oz which is apparently the 31st percentile. The physician who read the report said it was normal but my OB said she's a little small. I am now almost 32 weeks and scheduled for another growth scan next week because I had COVID at 29/30 weeks and it can "worsen the problem". I see a different doctor each visit and I feel like they are all telling me something different. What did your babies weigh around 27 weeks and if small, were they IUGR or just smaller babies or an average weight? Thank you!!
