S.H.
I am sorry for the losses you have suffered. This isn't a question that anyone but you and your wife can answer. It is different for every couple and you guys need to talk about what you feel before you start trying. Of course go to the OB/GYN before you decide and if you do start trying I would suggest being relaxed about it. Don't schedule sex, check ovulation etc. It is so much easier if you just enjoy each other and let nature take it's course at least for a little while. I found if I stressed about getting pregnant it just added to the fear that my body couldn't carry a child. Good luck!
