Michele, my heart is absolutely broken for you both. I cannot imagine a more difficult thing to go through. I am sorry beyond belief with the loss of your beloved babies.
Don't feel guilty though. Your body just cannot have a baby for some reason or another. Maybe the doctors are stumped too. You will make the most loving mommy in the world. I urge you to ***please*** consider adoption. My brother's adopted and there is no difference at all between me and him. Adopt a baby and you'll have the family you so desperately want.
Michele, again, I am so terribly sadneded by your tragic loss. Please take all the time off work you need to. You cannot possibly go back after such an emotionally and phycically draining event.
My thoughts are with you and here's a ((((HUG)))). You are not alone. We all love you sweetie.
