Fetal growth “borderline small”?

Just wondering if anyone has gone through something similar. I had my anatomy scan last week on the 27th at 19w6d and baby was 11oz. They said in my notes that the fetal size was appropriate for gestational age by weight. I did notice individual measurements were a few days behind. They couldn’t get a few pictures that they needed so I went back for another ultrasound today at 21w3d and baby is 14oz and in my notes it now says that fetal size is borderline small for gestational age (10-25%) by weight. I have a doctors appointment on Tuesday so I will definitely be asking all the questions but I was just wondering if anyone else has experienced this and everything turn out ok. I suffer from anxiety on a regular so this is really stressing me out and having to wait until Tuesday is making me anxious. Any input would be greatly appreciated! Thank you!
