Hi Turk,
I am having growth scans for 2 reasons.
Due to my high BMI, adn also as we dont have an accurate ( or anywhere near approximate) due date.... or due week. lol

But I did have to ask ne of the doctors why I was having these growth scans. So annoying when they tell you that they want you to do seomthing.. yet they won;t give you any reason why!

Good luck with all your scans and the rest of your pregnancy!
