HI V.,
So sorry for your loss. My first pregnancy ended in miscarriage (at about 6 weeks), and likely there was some genetic problem with the baby. I conceived again two months later and have a wonderfully healthy child, who was born when I was 41.
Talk to a genetic counselor to assess the risks in future pregnancies. It's a tough call, I know. Talk with your husband, and decide how you would proceed if you conceived a child who ended up having limitations. Only you and your husband can make the choice for your family.
Having said all that, even though the risk of genetic abnormalities is dramatically higher for us "older" moms, the overall risk is still fairly low. (Check with your genetic counselor, but I seem to remember that the over-all risk for most random genetic problems is in the single digits. Do check this with a professional, though)
Best of luck to you!
C.
