Is my body broken

Well i had a son in 2019. Come jan 2021 i ended up with a miscarriage. My cycles have been all over the place. Last month i tired provera to make my cycles happen. My dr said if i loose some weight might help me ovulate. I cant seem to ovulate on my own and im getting so upset. I also tried the metformin and if didnt work. Its going on 8 months now since my mc.. idk what to do anymore honestly. To conveive my son i had to do clomoid and metformin together but b4 my mc i conceived without anything.. .why...

Words of encouragement would be helpful cuz i feel broken...
