I am 13 weeks today and had my NT scan this morning from a very experience sonographer at the hospital.

At first glance he said he is guessing its a boy, pretty sure as the area between the legs was "bulky" which would be a worry if its a girl.

He went back there later on and said "look there" Definitely a bump there so "I would be totally shocked if it WASNT a boy".

Well, my question is, has anyone been told similar and then been wrong at the 18 week u/s or beyond?
