Measurements.... any words of wisdom?

[Goatlady5812]

I’ve had a few early scans due to problems... my last one ten days ago baby measured at 5w 3days heartbeat seen on normal us not vaginal.. back in today... good strong heartbeat but baby only measured at 6w 2 days? So only grown by 6 days in 10. I’m not panicking as such just more curious. I date myself at 7 plus 4..... and I’m pretty sure on my dates. Thanks muchly in advance. Xxxxx

You can be 100%on your dates, but you don't actually know for sure unless you saw your egg release, fertilise and then implant.
Implant can happen early or even really late, which would explain measuring behind your dates.
And they grow so stupidly quickly with no real plan at that early stage, so one day it could be measuring 4 days behind, have a growth spurt and the next time be measuring 2 days ahead!
As long as growth is happening and heartbeat is there, don't worry on dates and measurements
