Anyone terrified to get pregnant after miscarriage

I just had my obgyn appointment and the doctor said basically something 🧬 went wrong with the baby and it just stopped growing and aborted itself . She said my uterus looks amazing and I did not need a d&c . She said to wait for my next af to start conceiving, but I’m terrified for another loss .. anyone have a successful rainbow after a miscarriage? If so what are some helpful things you think you did to have successful pregnancy ?
