I have to go for a growth scan next week and Im kinda worried about it as I dont know much about them. I was told under no circumstances would I have more than 2 hospital scans, so since being scheduled for the growth scan, ive started to become a bit weary! This is going to sound silly, but what are they for exactly? what do they do at these scans and what are they looking for? consultant told me that anyone with a BMI below 19 before pregnancy, is usually scheduled for growth scans- but can they find abnormalities on these scans that were not picked up on the detailed scans? what would be the chances and how many of you girls have had one before?
