Michelle - I am pleased that you have made a decision - no matter what anyone says, as long as its the right decision for you guys.
I think its a good idea to do the bloods again, and I dont 34 is going to affect the odds that heavily. I know over 40 it gets ridiculous, but I thought under 35 and you were still not too bad?
Good luck, and I think you guys have made a brave decision. Its not your family's call,, its yours and whatever you decide is OK.
