Small bump

I'm 37 weeks and 6 days today. I had a midwife appointment and my bump is measuring small. I'm going in for a growth scan later today. My partner was with me at the midwife appointment and he hasn't spoken to me since. He's really freaking out. I can tell. He lost his brother to trisomy 18 a day after he was born so I think this is bringing up a lot of those feelings.. it probably doesn't help that the ultrasound we are going to today is at the same place his brother had so many tests done

Edit: Scans show his overall body size is normal but he has a small stomach. My partner is still very upset and I feel so helpless :( I don't know how to help my baby or my fiance and I'm trying so hard not to get stressed so I don't make it worse but I just don't know what to do
