Finding out the sex

Hello ladies!
Congratulations on the bundle of joy!!! 
I went to the doctor for my sonogram and I wanted to know if I can know the sex but the tech said it might be early but we tried anyway. She said from her prospective it looks like a girl but it's not clear enough at 12wks.
My question for you ladies is how early did you find out what you were having??? 👼🏽👼🏽👼🏽👼🏽
