Gender reveal gone WRONG!

I went to a sneak a peek place to find out the gender at 14 weeks. They said, "ITS A GIRL!" I was so thrilled as this is my last baby and I wanted the last to be a girl. Well, today I went to my 20 week anatomy scan. The ultrasound tech said she saw it was a girl but couldn't get a good picture for me. The doctor came in to check behind the ultrasound tech, all normal procedures. She then asked me, do you want to know what you're having? I was like, oh I already know, were having a girl. She was like, you're not having a girl, it's a BOY. I was stunned. I couldn't believe it! We have already announced that it's a girl. Any fun ideas to announce that we were wrong? I'll attach the pictures where we found out it was a girl and then today's showing it's a boy.
