lol. no nothing will be wrong with her nose. It can also happen if they ange it wrong toward her head, can look like a huge chunk out of her head is missing. I would say its just the way the scan was. Meaning.. ur u/s lady might have gone down like a mm to low and the scanner might have looked a little up bubs nose which can make it look like abits missing. If the point it right up her nose its scary coz it actually looks like she has no nose!!!! I hope that made sense.. i had a look at ur scan pics and there is NOTHING wrong with her nose
