Hurt and confused

So I have off and on got slight positives and also negative and then my period comes. I’m so hurt every time cause I want to be a mother so bad. My husband is super supportive but I feel like I’m letting him down as his wife. I have PCOS and Endo and have told it will be hard to conceive. I try to have faith that trough God miracles can happen and that to put this in his hand but at the same time I just don’t understand why me? Please pray that I see hands in this and feel him near and have faith in his plan.
