3D Ultrasound at 15w5d? HELP!

Sami β€’ 🌻1.31.18πŸ’™

How many people have had luck with finding the sex of their baby at the 15 week mark?? We have a 3D ultrasound scheduled for that time and I've heard so many stories of women being told it's a boy because their girls labia was still swollen etc so I'm really starting to second guess this whole thing! πŸ˜† help please!!!!
