Anxiety after scan

I was always told up to 2 weeks ahead or behind is fine because the due date is just a estimate.

Och yes, I had some measurements 6 days behind, at one point her head was 8 days ahead.. but also going by their measurements she was 90th centile.. but in reality she has followed 9th centile since birth although has dropped slightly recently. So honestly dont worry, they are not completely accurate, its more so they have a general estimate to go by each scan. 💜💜

Yes, a few days outside of growth trajectory based on due date is absolutely within the norm. Nothing to worry about at all if that’s the only thing noted.

I had a scan 13 days ago where I expected to be 5w6d but was measuring 6w3d. The sonogropher said that - because they're dealing with millimetres at this point - the weeks tend to be accurate but the days might be slightly out. I have a follow-up scan tomorrow and keep reminding myself that I might be measuring a few days behind 8w3d for that reason, as it's subjective.
