Worried about getting pregnant again

My first pregnancy was a missed miscarriage at 8 weeks 3 days. My second pregnancy was successful and my little miracle is almost 7 months old now. I want to have another baby but I'm so worried I'll miscarry again. Like it's it's turn again. One miscarriage, one healthy baby and next... I know this isn't healthy thinking but I cant help but worry that it'll be too good to be true for me to have 2 successful pregnancies in a row since I'm prone to miscarriage. Ugh it'll just tear me apart again if I lose another baby. Planning to start trying again this summer. Going to do everything to get my body ready and healthy to carry again prior like last time. (1st preg was a surprise and I had just stopped taking my birth control which probably screwed with my hormone levels I'm guessing) Need some positive words to help me keep my head up no matter what happens. Has anyone miscarried w/their 1st and had more than one successful pregnancy after w/out miscarrying again??
