Fundal measurements

De

I know we’re not supposed to think to much into it because it’s not a good indicator of how much baby weighs but what if it’s been the same for the last 2 appointments. My fundal measurement has been 37 since I was 32 weeks I’m now 35 iv also only gained 2lbs since 32 weeks. Is this normal? I feel like I shouldn’t be hitting a Plato yet
