Crown rump length grown 5mm in 1 week, can measurements be off?


Hi girls,

So I finally got to see my little bean last week, Wednesday night, measuring 4mm, so around 6 weeks 1 day gestation.

I had another scan this morning, crown rump length measuring 9mm, they put me at 6 weeks 5 days, so only 3 days off where I should be, and some websites say 9mm equates to 7 weeks gestation anyway.

My only worry is the crown rump length growing 5mm in nearly a week. Has anyone else had this happen? Can the measurements be off a couple of mm? I know the crown rump length is supposed to grow 1mm a day.

Thanks xxx

The 1mm a day is a guideline not a target,
Sounds good to me x

This early on the measurements can always be off.

Different websites say different things. Some say 6 weeks plus the measurements in mm, so yes 4mm would be 6 weeks 4 days. Then others say its about 7 weeks 1 day. Very confusing.
