Serious question.

So, at my anatomy scan I was told that everything was fine and she was healthy. No issues. I just read about a girl who was also told that there was nothing wrong but when her baby was born she had major skeletal issues, basically she's a midget. I'm really scared about the health of my baby I haven't had an ultrasound since week 20. I'm 34 weeks now. I haven't been eating incredibly healthy either so I'm scared that is bad for baby.
