THe VCGS are quite good. When i was tested for CF when pregnant with DS1 it came back positive that i had the gene, but luckily DH was negative. All of my immediate family was able to be tested for free, but as my sister has already had her children and they are all fine, no one chose to have the testing. When my two boys are old enough (18+) i would get them tested to see if i passed it on. I think its good to know what you are dealing with, and what you may have to deal with in the future. From reading some other threads, PGD is VERY expensive, ie. much more expensive than "normal" IVF.

Good luck! J. Xoxo
