Gender scan at 14 weeks!

Help! I had my 14 week scan yesterday and the tech went in between the legs and I could immediately see what I thought were boy parts so I said is it a boy? She said looks that way but the cord is also between the legs 🙈 she said she would lean towards it being a boy but not to buy blue things just yet... I was shocked as I have done the nub theory and posted pics of scans on this site and came back girl every time.. I even posted scans of yesterday scan and people think girl 🤷🏻‍♀️ I’ve no potty shot but I guess I’m just wondering has anyone else been in this situation and it turned out to be a girl? Help plz! Thank you x
