Stupid question ....

So, I had another growth scan , I’m supposedly 35+6. Everything’s going fine, arms and legs are shorter and are in the 3rd and 9th centile whilst everything else is in the 30-45 centile.. whatever, I’m not concerned he’s still growing considering he went from 1.9kg to 2.8kg in 3 weeks lol fatty... then she says I’m growing a week ahead at 36+6. So does that change everything? Am I considered 36+6 now or still same lol?
