Gender prediction test?!

Lisa
So I don't want to find out the gender of the baby. I want to find out the day of BUT I do like to do fun gender prediction test. I had blood work done at 10 weeks and my OB/GYN knows the sex already but I'm not giving in ❤️😝. Placenta was on the right per US tech so ramzi method says boy. What other fun test are there?
