I want to be pregnant so bad.

Month after month for the last 3 years it's been very disappointing, but now when aunt flow comes to visit I'm like "whatever" it doesn't bug me as much anymore, i don't even get my hopes up anymore, my husband and I just want a baby so bad..it would be so great if we could just have a baby. My husband and I try and try just to get let down month after month. I'm starting to lose faith in this whole thing, I'm trying not to but sometimes it's hard. Maybe I shouldn't be mad at God for not being pregnant.
