Infertility ?

So ive had 3 mc. First time i had ectopic pregnancy. Piece of my right tube cut off. Second time 9 weeks no heartbeat. Third i was 5 months, and again no heartbeat. It seems i can get pregnant and not so strongly but i can just can't seem to hold onto a pregnancy. Has this happened to anyone? Share stories of what y'all were told or anything would help. I feel like i just cant have babies and it realy hurts. Since a kid I always imagine myself with a family !! And docs ALWAYS just say "you seem fine" "you're perfectly healthy." Even when i tell them my MC. What can i say for tHem to ge to lookin or helping me
