British Mommas - Anatomy scan

So my 20wk scan was originally booked for Friday 29/11 (would be 20+6wks) but I’ve managed to move it forward to this coming thurs 21/11 (will be 19+5wks)

Only moved it as it would be easier with work to do it this coming week and to be honest I didn’t think they’d have a slot but they did so thought why not.

I’m just now thinking and worrying a bit as I don’t know if this would be too soon. I don’t want to turn up and be told they can’t see anything and to go back so I don’t know now.

Any of you mamas had your anatomy scan before 20 wks exactly? And was it ok? I know the NHS site says anything from 18wks to 20+6wks but I don’t know why I’m getting so worked up about this now just wanted to hear from your experiences. 💕
