Nub theory, skull theory? *Edited

Nu

*update 2, we found out today our baby is a boy!

*edited to update, I talked to my husband and told him I want to find out the gender, and he said he's fine with that, apparently he wasn't as set on it as I thought he was. Out next appointment is in 2 days so I will update if we could see the gender to see if the commenters were right!

We decided not to find out the gender and I am having a hard time with that decision, so of course I'm playing around with all these theories of guessing babies gender 😂 I am going to try to convince my husband to change his mind but he seemed super stoked to wait until baby is born, we could find out in 5 days at out next appointment if we wanted to! Picture was taken at 11 weeks 5 days.
