Belly size

Samantha

I went to the hospital today for fluids check up. They told me my daughter is 4 pounds right now, I’ll be 34 weeks next week. Is this a good size for my daughter right now? Then I had my two weeks check up with my OB he said if the size of my size isn’t going up I’ll have to go back to the hospital for another fluid check.

Any advice? This is my second pregnancy and I thought my belly would be bigger
