Gender Blood Test and 12 week ultrasound!

Any of the ladies due in September know the gender of their babies yet? I was going to take the harmony blood test at 12 weeks. I'm 10 +1 now. With my first we could see on the 12 week ultrasound his penis! I want to be surprised ( and have a gender Reveal but I'm afraid I will see something at my 12 week appt! We were going to have the harmony test results given to my daughter and she was going to plan the reveal. What's everyone else doing?
