Small in growth

Kellie • Kellie (Hope & Faith) for # 3

So I'm 32 weeks 3days and had an ultrasound sound today and the doctor came into speak with me concerned about the measurements, saying my baby boy is measuring about 2 weeks behind normal size. Now also place in mind when I found out I was pregnant I was considered to be small framed, so she is thinking it just because I'm small. So I have to give back in 3 weeks for another ultrasound to make sure its just the growth curve.

I literally feel like I cant get any bigger, but everything else in it he ultrasound looked good, hes practicing breathing, heart rate is standing strong at 160, but instinctively still worried.
