Baby or adoption

When I was 24 I had emergency stomach surgery and was told if I wanted to get pregnant to start trying. My husband and I are now 29 and still aren't pregnant. Two years ago we started the adoption process and stopped because I became very sick. I went to a doc appointment for my stomach and he says on his end I'm good to go. We had been told for four years I can't get pregnant. I'm not sure if I want to go through infertility treatments and not end up with a baby. My health had been a roller coaster and I just don't know what to do.
