Measuring a week behind - Any experience?

[Mrsjaytee]

We had our early preg scan today.

They seen a sac & yolk BUT we should be measuring 6+2 & we are only measuring 5+2.

We know exact dates obs due to embryo transfer dates, but we also know this was a high risk embryo due to the testing results. We were even surprised to get a BFP.

At 5+2 it’s too small to see a heartbeat, but obs it should be bigger & further.

Has anybody else measured a week behind early on & it’s been ok, or do we think we embie tried but has stopped?

Rescan booked for 2
