Gender reveal party

So I had the blood test done this week and I'm planning a gender reveal party. They said 10-14 days so I am planning for the eve of the 14th day. Hoping to get results in before then to plan to have a cake done. If not what other last minute reveal ideas have others done? If I get the results that day I'll have to be somewhat quick :) very excited, my mother is flying in that morning 💕💙💕
