Small babies?

Hailey • 21 • Amaria Rae born on 6/6/2018 • Type 1 Diabetic

So I went to my appointment today I’m 31 weeks 5 days and they did a measurement scan on her and said that her weight is in the 41st percentile, which isn’t that concerning but her head size is 8th percentile and her thigh/leg area is 2nd percentile. They didn’t really seemed that concerned and told me “they’re gonna monitor it” and that it’s probably because I’m only 5 feet tall, but I can’t shake the feeling that something could be wrong or off. Did any of you have something like this and baby was fine? Like is she just going to be super tiny?
