Frustrated and on Edge

My doctor was worried about me measuring behind, so I was supposed to get a growth scan and have my normal check up today. She ended up having to reschedule to meet with me tomorrow, but I still got my growth scan today. When I asked how much she weighed like I always do, the lady said, "She will go over everything with you tomorrow." The lady has told me her weight at every other scan, so now I am on edge and aggravated. I'm a tiny person. My husband and I were both tiny babies. I'm trying not to worry, buy I just feel like she made it sound like there was something wrong.
