Am I a fool to think I still have a chance at a healthy baby/pg??
No more a fool than me. I'm yet to have a healthy, live child. All ours have had a fatal condition and I was younger than you when those 3 were conceived.

Pregnancy is a hope, not a promise. All we can do is hope and pray and try again. If you're not yet emotionally ready, then you can wait a while.

As N2L said, there are no guarantees in life. Miscarriages are hard. I sure dont want another one, but I have the view that if they're early, then mother nature is doing her job. We all have our limits and I dont think we know what they are until we get there.
