Can't help but worry

👣👣💙💙michelle💙💙👣👣
I can't help but worry about my size I haven't grown and I actually feel smaller than I did a few,weeks ago I've only put on about 10 pounds I'm 23 weeks today I'm terrified because of this fear that I'm going to have a really small baby or my baby will be sick because I'm not growing in my stomach at all I've had ultrasound and they are all fine and I listen to his hb at home but still wondering why I'm not growing and why my stomach is squishy still at almost 6 months
