So I posted this in the nub groups but got no response so thought I’d try here…

This is my second pregnancy and I’ve only just found out about nub theory 🤷🏻‍♀️ I’ve tried to google it to understand it and at first I just thought if you could see a little “tinkler” then it’s a boy but if you don’t see anything then it’s a girl, but as I started researching on it started talking about angles of the spine or something and something about 30 degrees which is really confusing me. So anyway just wondered if anyone had any idea and could maybe predict this (13 weeks scan) I won’t have my gender scan until October 13th and can’t wait until then 🙄
