Insensitive ultrasound techs...:/ :(

So I went for my ultrasound last Monday and I found out I'm having a girl! Yay! But, the Lady checking my baby and everything had to make the comment that my baby looked skeletal... Like really lady? :( my baby girl weighed 1lb 8oz but said that... With my LMP being on Dec. 9th and being that my lil one was measuring at 1lb 8oz but saying I'm 2 weeks and 2 days behind from my due date with my LMP its confusing as to if she looked at my baby and using my LMP as a guide first then re measuring and seeing my baby was 23 weeks and 3 days...idk maybe I'm being too cautious but I'd rather make sure my baby is OK than not, so I go back next month, July 7th for a growth scan, what do you y'all think about it? Is it normal for my baby to weigh that but still look skeletal?
