Bubs weight at 32w

Just had a growth scan and they’ve estimated baby is 5lb 3oz at 32 weeks; they said that’s fine but I’m freaking out a bit as that seems quite large already!! Plotted on the graph it looks just above average tho, is it because I have GD and was overweight to start with that the baby will be bigger? My first was 8lb 11oz when born but I didn’t have GD then x
