GA AUA ??

Brenda

I went to see my dr today he said 4 wk 6 days. On the ultrasound it says that with LMP beside it, right under it says GA AUA 5w5days what does it mean? Does it mean I’m further along then I thought orr

Also due date based on LMP was October 8

But AUA says October 3rd, dr said the 8th is my official date .’
