22 weeks plus 1 day

When I went for my 20 week anatomy scan baby was lying awkward (face down) so lookin down at my feet and cause they couldn’t get measurements of the spine I had to go again 21 week plus 5 an still lying the same so gave me another appointment for tomorrow to see if they can get the measurements they need my question is has any body had the same thing happen to them an when did baby finally flipp round haven’t been able to get the gender either probably cause of it I know that isn’t important but would jus put my mind at a bit of ease thank you
