20 week scan - gender guesses please!

Hi Guys!
So we had our 20 week scan and my husband didn't want to know where as I was much more curious since we already have a little girl and I was pretty confident in my ability to tell girl or boy. So while my husband looked away the tech gave me a quick shot and I saw 3 lines and said yes I know what it is. then we come home and I start looking over the video well to my surprise I see what I believe to be boy parts popping up, so my question is, is there any way this would still be a girl or is the definitely a boy? We have no preference but it would be nice to have one of each so before I get too excited I wanted to share some pictures and hopefully some of you more skilled ladies (as apparently I am not) can help me out! Thanks so much in advance. The first couple picture are looking from the belling down, and the last couple are potty shots with the legs close together

Anyone at all?

Hello,
I am not very good at gender but these pictures are difficult to determine from I would say 50/50 as 4th picture has 3 lines which looks girlish but then picture right above looks like a boy, are you going back for more scans?

Difficult pics, some look girly, the last one looks boyish. An 12-14 week nub pics?

Can you post the video on somewhere like youtube?

No sorry I am trying to figure out how to cute he video down its too long to upload. What do you think that protrusion is in the first 3 pics? Could that be the cord or something else that is throwing me off and it is a girl? Thank you all soo much for your input I really appreciate it
