Miscarriage

I have one child, after my first child I got pregnant a yr after my son's first birthday.. I did have an abortion due to personal reasons. After that I have been pregnant twice in hopes of having another child but I have miscarried both times.. Yes, this is with the same child's father with the first. I feel god is punishing me. We are at a age and time in our lives were we want another baby but it seems so impossible to get pregnant and have a successful pregnancy. Is there anything I can do to help have a successful pregnancy and complete my family
