Early gender diagram

Alexandra • Baby #2 due Aug 2018
Someone put up a diagram of how similar genitals look before 16 weeks. A friend of mine is obsessing to find out at 12 weeks the gender but I want her to see that a boy and girl look similar at that stage. I saw it on her last week. Wish I saved it then! If anyone has it and wouldn't mind sharing it, that would be great. Thanks!
