Measuring Large

Samantha
So, 3 weeks ago at my last appointment I was told by the doctor when she measured I was measuring a little large. Anyone else have that issue? It's been bothering me for weeks. I'm currently 26 wks 4 days and I'm wondering if I should be worried? The dr didn't seem too concerned but wants an ultrasound in a week to check babies growth. I have serious anxiety and I'm just wondering if baby is growing too fast or I'm just gaining too much weight too soon?
