Gender at 10w6d?

Megan
So i went in for an ultrasound today just for peace of mind and the tech said she could see the parts forming and shes sure its a girl. I know it might sound selfish but i have two daughters already and really wanted a boy this time and im crushed. Please keep rude comments to yourself but i want some words of encouragement im pretty devastated and ready to lock myself in my room and cry isnt it a little early to tell gender? Is their hope for me to have my little boy?
