I believe you and your DH are living a blessed life. Not being able to produce a child can cause problems for you and it becomes difficult as the life without a child can be boring. The thing becomes difficult and in third world countries, the position of women in the family may become weak. I know what you are going through. This difficult time will pass and you will be able to make your life happy. Stay firm and go for surrogacy if you can afford it. It will make things easy for you. Your life will change. I have a live example of my friend whose life had a miraculous turn after she was blessed with a child.
