Question, need some hope

Just wondering how long it took everyone to want to try to conceive again? I experienced my loss over the weekend and the thought just terrifies me. I know I still need time to heal... I'm not sure how this feeling can go away but I've always dreamed of being pregnant. Does this fear of something like this happening again ever go away? Just been feeling lost and trying to see a light at the end of the tunnel. Any response is appreciated!
