I had exactly the same after a growth scan this week, they was worried too small and went back on Friday and now apparently showing at 5lb 14 at nearly 35 weeks. Although weight and most things average his tummy is showing at the 95th percentile so they want to test me for GD. They did mention it may mean bringing him out earlier x
Had similar this week 31+1 midwife measured bump as too small went for growth scan ended up having to see the consultant as baby too large. So have to have another gestational diabetes test and if that comes back clear again they will scan again in 4 weeks and he mentioned if growth carries on at this rate possible induction at 38 weeks. So will wait and see!
My son was measuring 4lb at 30 weeks so would be the same as you. But they let me go until I was over 42 weeks which now knowing they shouldn’t have as he was too big and got stuck. They probably won’t induce you until 37 weeks. I’m 31 weeks with this one and have only had 2 appointments in total, so we will see how big this one is on Wednesday x
