Nub guessing - when is best ?
Im due my 12 week scan on Jan 22nd but looking at my dates I will only be 11+5. Im aware that nubs can change slightly between then and 13 weeks and so im wondering whether its worth trying to put it back a week to nearer 12+5..... though to honest Ive not seen a nub on any of my previous scans as i think here they are careful not to show too much and its all very quick so i dont want to anxiously be waiting another week for nothing. Im a bit undecided and wondered what peoples views were - how much can change in that week ?
