Gender confusion

Hollie
So today I went in for a regular check up today at 29 weeks & the doctor asked me what I was expecting & I said a boy (me & the fiancé found out at 20 weeks at the anatomy scan) and she said according to the paper work he is a she ! But the lady doing the ultrasound said baby boy 🤔 I am so confused .. Thankfully she was kind enough to schedule another ultrasound to find out fersure . I'm almost positive he's a he though I saw his genitals on the screen and that looked like all boy to me !
