My husband and I tried for 4 months to get pregnant and finally it happened

We were right at 8 weeks when I started spotting but it wasn’t very much so my OB nurse wasn’t concerned until it continued and my levels dropped we found out we had lost our baby and I didn’t realize the pain that comes with loosing someone you never even met but its agonizing and no one really gets it. My first appointment after the miscarriage is in a few days and I feel like I should have a list of questions to ask the doctor but my mind is blank and I am still numb. I never thought it would happen to me. Do you guys have any advice or can you think of any questions I really need to ask my doctor to prepare us for our next pregnancy?
