Nub or skull theory?

[Aangel1234]

So I have no idea what I'm looking at for the nub and cant seam to see one, can anyone else see one and what baby maybe? Or by the skull theory what would you guess. Were either of these theorys correct for you? x

Look up nub theory online. There is lots of good info. This is the theory that doctors abroad use to estimate the sex of a baby at around 11-13 weeks - it is a real thing. Obviously they know what to look for throughout the ultrasound so it's more accurate than you trying to figure it out from one picture but sometimes it is clear. Skull theory has much less evidence to support it.
