Hi Gigi. Sadly all I know of amnios are what I learnt at Uni, so I'll probably be less help than anyone else, but just want to let you know I'm wishing you all the best for this! There is a small risk to the baby, but it is small, and even smaller now you are in your second trimester. If you want any info on the genetics side of things I'll drag up some info for you, also check the results for a level of mosaicism (a mosaic baby) - the people there, or giving you the results, will be able to explain this very well, but basically this is where some of the baby's cells are Downs and some aren't, so can change the level of the severity of the Downs syndrome. Hope you get through all this ok.
