Incorrect gender told at ultrasound?

So I paid to have a private gender ultrasound done at 15w3d. She had to really work to get a look at the goods. She told us a boy. And while we were there I kind of agreed. I didn't see the classic three lines a girl would give but I didn't see the clear defined penis either.

I have two prior boys. And at 14 weeks they had vey clear and well defined penises. Like I was "screaming boy." This time it appeared like three dots that had the middle dot that stuck out a little farther than the rest so she called it a penis.

I can't help shake the feeling that maybe it was the clitorus that may have been still swollen and was making it appear as a penis.

And no before everyone asks I don't have an image of the "potty" shot bc she wouldn't give me one which makes me question it more.

Has anyone else been told boy/penis and it as a girl this early? Probably just me really wanting a girl lol
