Heart broken want a baby so bad

Last year in September i had my 2nd miscarriage. One when I was 17 and last year when I was 19 I was 9.5 weeks that one. I'm worried now that I'm not going to be able to have a baby now.. like can my body not handle a child !? I don't think I can go through the trauma of losing a child again and it's kinda effecting my relationship with my boyfriend now cause my ex ended up leaving me and cheating on me because of it. Did I do something wrong 😭😭 my heart is still a mess💔💔💔 please help
