Need some reassurance

Okay ladies, I’m officially 36w4d and I went into my MFM for a growth scan and BPP today and they told me everything was measuring good except my mans little belly. It’s measuring about 2 weeks behind and he only weighs 5lbs12oz roughly right now. I’m trying not to stress too much, but my mind can’t help but wonder😭 I go see my OB this afternoon and I would assume we will discuss the scans. Anyone else have this happen? What was the outcome for you?
