Belly measuring small

Mo • Mama ×3 ❤

Has anyone else had their belly measuring small? I am 34 weeks and belly is measuring at 30. I've been about a week behind with every measurement but now it is about 4 weeks so the doctor is referring me for a growth scan. I haven't grown since my last appointment 2 weeks ago. She said baby could just be small but they want to rule out other things. I know this way of measuring isn't very accurate but I am still a bit worried.
