Fertility treatment

Hey there. My husband and I are trying to conceive for years now. We have undergone fertility treatment and today got the results. It's unexplained lesser fertility. So now the advice is to do IUI with hormonal treatment like clomid. We feel like it's a tough choice. I think there might be risks involved in hormonal treatment and personally it feels like it's unnatural. I also believe that it might not be Gods plan for us to do so. So I am looking for opinions. What would you choose? Thanks in advance.
