I would probably leave the IVF thing alone now, you know how you feel in your heart and you can deal with it when the time comes.
I agree with this. If, when the time comes, you still are not comfortable with it then it's time to talk to her about it. But leave it alone for now.
She may come to her own realization that it's not the right thing right now. You never know.
