Miscarriage last month... how to move on?

My hubby and I weren’t TTC, but we ended up getting pregnant last month. It was surprising but exciting, and we were ready to face the challenges that came along with a child. Unfortunately, I miscarried at about 5.5 weeks, and we were devastated. I haven’t started back on birth control because I don’t really want to. I’ve wanted to be a mother for my entire life, and now I’m just terrified that this will be our struggle forever. My Mom’s first pregnancy was me, so it’s a painful pill to swallow that this is how my first ended. I was doing everything right: the prenatals, everything I needed to do, I did. It’s just been a really trying time for me and I’m not sure how to go forward. I’m not really sure what I’m asking you ladies.... I’m just in pain.
