Nub theory 11 weeks

[bumbledeedum]

Just wondering if anyone knows how early you can guess at nub theory? Had a scan today that dated as 11+1 but not sure if it's too soon (or if there is a nub visible as I'm rubbish at spiting then!). Hopefully photo attached!

Hopeful bump

Anyone?

The nub can rise at this point so I wouldn’t want to say. Can easily say girl now and in 2 weeks it’s clearly a boy. That said My friend had my scan at 11+5, assumed girl from nub theory and had a girl.

Ah I did wonder if it could still change. I have another scan next week at 12+1 so hopefully might be guessable then!
