Anatomy scan ??????

So we went in for our anatomy scan & told the tech not to reveal the gender to us because we are having a party tomorrow. The tech asked us to close our eyes 3 separate times when she was trying to identify the gender. The first time she said she needed to come back to it then the second time she just said ok you can look now then for the last time she said she wanted to confirm once more... so I’m thinking she should have seen if it was a boy within those two times. I almost felt like she was guessing by the third time? Or maybe trying to throw us off? Because Witt my first son ( same tech) she was able to tell right away. No question about it. I know that sometimes babies hide there gender pretty well so it could have been difficult for her this time around.

What are your thoughts???
