11 weeks- doctor says it's a boy

Kenia
 I went in for the genetic testing yesterday and my husband asked for an ultrasound since he hasn't seen the baby yet. Heartbeat was between 150-160 and on the ultrasound she said she saw boy parts.. Anyone else have their doctor guess early and find it was right? I have 2 boys already.. Did Ramzi with this one and they said girl lol. I guess nothing is ever guaranteed until birth
