Which to pray for, a child or God’s will...

My husband and I have low chances of becoming pregnant. He has health problems that have caused our chances to be decreased. Because we want kids and have been trying for a little bit he confided in a doctor. He doesn’t want our families to know so I have no one to turn to. With this being said, he is on medication that is suppose to increase our chances but we have still not concieved. I know it is going to take time. We are tracking ovulation and all of that stuff. I know it bothers him and i try really hard to hide the fact its killing me. I broke down the other day and all he could do was hold me and tell me “this is our month”. How does anyone else in my situation handle this??? I want God’s will but i want a baby also.
