Gender guessing fun ??? Xx ♡♡♡

Hey ladies :)

Im currently 10weeks & 3 days :D im sooo impatient and cant wait till my 20week scan so we can find out what sex the baby is :) but was wondering what a some fun goofy ways on predicting the sex of your bubba before the scan. Can I have what its called and the instructions to please haha :)

Just so I feel like I know then I can compare with the scan and see if they work !!! Xxxxx
