13 week ultrasound questions

Tech said angle was girl. He did not see a penis. But he said he couldn't tell in 3d if it was a scrotum or swollen labia.

Would a scrotum that has dropped made the angle look girl?
If the scrotum has dropped, would a penis be visible?
What are the odds he saw between the legs and saw a scrotum but no penis after 30 minutes of searching?
What are the odds of a girls angle at 13 weeks being a boy?

I will post pictures when I get home but feedback would be nice. Right now he says 50/50 because angle suggested girl but he's not sure if the 3d was scrotum dropping or swollen labia. Again no visible penis but I am only 13 weeks.

Wish I could help. All I can say is at my 13 week scan with this baby, we could see a penis. I know 13 weeks is really early but maybe since you didn't see anything means its a girl. With my 2 girls, there wasn't anything to see between the legs even at 13 weeks. Good luck. Hope you get what you want! :)
