Should I trust the ultrasound technician?!

​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​So I'm 12w6d but measured at 13w5d. I asked the sonographer to take a peek at the privates and tell me her expert opinion on what the gender might be. She said 90% its a girl. Do you really think she can tell this early? At least with a 90% certainty?!?
