Nub shot at 11w2d - totally useless?

I keep reading that before 12 weeks, nub shots are useless... is that really true? What about 11w2d? :fx: I have two videos of my NT scan that have multiple, multiple very clear nub shots ... but are they just worthless? Has anyone had an obvious boy nub at early-mid 11 weeks?

I think if you have a nub that is on the rise at that stage it is unlikely to flatten but if u have a flat nub it could rise.

Agreed. If bub is measuring ahead and the nub is obviously boyish, it may be a boy.

Nope totally useless.
