What is wrong with me

I moved in with my husband after dating 6 months. That was exactly two years ago and that is how long we’ve been trying. We don’t use protection just so we can conceive. I am overweight. For two straight months we would do it when we’d wake up, when he’d go to work, and when we would go to sleep. I thought it was stress so I did everything for 3 months so I wouldn’t get stressed but I started stressing out again and I don’t know what to do.
