Questioning gender

Lindsey
Help. I am 18 weeks pregnant with baby number three. My first two are boys, and were undeniably boys on ultrasound. I've prayed for a girl for years and finally found out at 15w6days. But I'm having a hard time trusting and believing it's actually true!!!! Would you 100% trust this photo?? I had planned to do gender reveal to my family this weekend.
