thanks baby amore, i think i understood most of what you said.

just to clarify one point (sorry i am slow) - is the 12 week scan you refer to, the Nuchal Scan?

thanks for going to all that trouble to explain all of that to me, the midwife probably said it all at the clinic, but my mind was racing - so much to absorb in that two hours, plus i have to concentrate ALOT just to control the nausea - i don't think it all sunk in. I come home and read books (all published in diff countries) and get myself in knots cos they use diff terminology!
