Trying again after miscarriage.

We had a miscarriage 2 months ago, first time pregnant and would have been our first baby. Since then my body seems to be returning to normal but me and my husband are both scared about what will happen next. We are afraid to open our hearts again to the thought of accepting another pregnancy then losing it. I was only 6.5 weeks when I lost it but as we were actively trying we developed an emotional attachment. Now we're both scared that it might happen again, and although we really want to have a family and we're ready to try again, I don't know how you let go of those worries? My sister has a 6 month old and when I see them together, although I love them both millions I feel a pang of loss wishing that was me. Can anyone offer any thoughts? Thanks 😊
