Constant state of fear.

Any advice for someone who longs to have another baby but is terrified of having a third miscarriage in a row? ☹️ I have a DD who is 4. Then we got pregnant again but found out at 16 weeks the baby had stopped development at 13 weeks. A year later we tried again and had a natural miscarriage at 5 weeks. My progesterone was low the third time. No idea what happened the second time. My life is a constant battle of wanting something so much but being terrified of it happening.
