oh Bella - forgot to say - My ob used to do a scan at each appointment - it wasn't very high resolution or anything - just to check heart beats. At about 12 weeks he told me he could take a guess at the sex and said it looked like 2 girls but emphasised it was a guess only. He was right though. So if your babies cooperate you just might get to find out what flavour you've got. Generally they can tell the sex pretty accurately at the morphology scan (usually 18-22 weeks)
