Ultrasound and Gender Reveal

Amanda • 25, Expecting baby #1 👶🏽 💙

Okay so I’m supposed to find out the gender Aug 9th and do a gender reveal Aug 10th. But my dr scheduled me another US on the 23rd of this month, I’ll be 17 weeks. I really want to know the gender but my boyfriend won’t be at that appointment, so my question is.... would the baby’s genitals be REALLY obvious, like if I’m watching the screen? If I can find out the gender can I ask the tech to put it in like a envelope or something? Any experiences? I don’t want to ruin the surprise, or find out without my boyfriend being there. If I do find out I’ll definitely do the reveal this month, I’m to impatient and anxious lol
