Tiny Baby

So I have a question. I feel so small to be 32 weeks today. I mean I was bigger with my son at 32 weeks. Any reasons anyone could think of?

This is me with my son

This is me now with my daughter.

Does does anyone think I look the same or close because the doctors had me worried not at the last appointment but the one before because they said she's in the 16th percentile. That if she dont even out then I will have to go to the high risk doctor. Please give me your opinions.
