Skull theory - gender

Hi, I am currently 19 weeks pregnant and I have my 20th week anatomy scan soon where I will know the gender but I just read about the skull theory and would like to know what you think of my scan at 15weeks 5 days, do you guess boy or girl? Btw I’m happy with any as long as he/she is healthy 🙂 please post your scans too if you like!
