Growth scan extra amniotic fluid

Je

So went for a growth scan at 34 weeks as I’m type 1 diabetic and was told I have extra amniotic fluid, she said it’s 26% instead of 24% they didn’t seem worried and said it’s common in diabetic women, but I never had it with my other two pregnancies! I guess I just wanted to know if anyone else has had this and it turn out to be fine or if not what happened, thanks in advance
