boy or girl

Eh, hard to say from a scan pic alone lah, even the sonographer sometimes cannot confirm until later! The nub theory, skull shape, all that memang can be misleading sometimes, so I wouldn't bet money on it yet hehe. Best to wait for the official 20-week anatomy scan if you haven't done it already, or ask your doctor to do the proper gender check when baby is in a better position. Anyway, exciting that you're so close to finding out!
