Feeling discouraged

My husband and I have been TTC for about 15.5 months now, we can’t afford to even walk into the fertility clinic (it’s $425 just to walk into the office to see the doctor). My husband keeps telling me that it’ll be our turn someday and that I just need to try and have faith, but every month it gets harder and harder to keep the faith that someday we will be parents. I just had an HSG last month and I read online that women have gotten pregnant following that procedure, so I’m hopeful that’ll be the case for us. I’m just reaching out for some support and encouragement, and if you have any advice for handling the heartbreak of not conceiving month after month please share, I’m just not sure how much longer I can handle these feelings.
