Long story short, the best date we have for our gender reveal is two days after my anatomy ultrasound... Right after I get into 18 weeks. If we don't do it on that day we'd had to wait atleast another month to tell our families what their first grandchild will be. Have any of you ever not been able to find out the gender at your anatomy US or were told incorrectly? I'm concerned to plan this whole reveal party and either not have or have to go back and change what information we were told
