Same here my bmi was 36. I had a scan today unfortunately baby was too active to get measurements so back for another scan on Wednesday.
I have my consultants apt on Tuesday, I don't think he will be giving me a scan, its more for him to monitor my pregnancy (I also have had cervical issues in the past). My midwife said its more procedure, just need a little more monitoring as potentially could have a bigger baby and pregnancy complications.
I wouldn't worry too much they just have to go through certain things with you to show they are doing extra monitoring x
