So, below are all the pics from my scan today - I don't think the sonographer got a picture of the nub (except possibly in the third one down?) as she didn't know what she was looking for, but any guesses are very welcome! I thought possibly I saw it flash past a few times with some stacking, but I don't know enough to be sure. I am 12+3 weeks today, but measuring 12 + 6.
Many thanks!!!
