How can I avoid a 2nd miscarriage?

La

I just had a miscarriage on my first pregnancy. They found it at 8wks but said the baby stopped growing at 6wks. My doctor assured me it’s nothing I did wrong and it was just never a viable pregnancy, but I’m so scared it’s going to happen again. Is there anything you can do to prevent an abnormality when TTC? I’m willing to try anything not to have to go through this again.
