ramzis method pic....any guesses??

any idea with ramzis theory if this is boy or girl?

This was NOT vaginal. if its not vaginal you need to mirror image it right?

I dont know how to look fot the ramzi theory, sorry, I hope somepne comes along and will help you. When you have a 12 or 13 weeks us than can I tell the gender by NUB and skull.
Goodluck 💛
