Williever - I'm sorry to hear ur DS has hfmd! It's horrible isn't it!
As for your transfer - I actually had hfmd myself two weeks ago right around when I ovulated - I am 4wks3days at the moment so it is def possible to fall pregnant with the virus... I guess only time will tell if it had any effect on the egg quality.

I hope u get some good news in a few weeks and your DS recovers quickly
