Struggling ☹️

My husband and I have been trying to get pregnant since we miscarried in January of this year. We've tried everything we can think of. My doctor has me on medicine right now and I have PCOS. I'm getting extremely discouraged and starting to want to give up. I have a six year old who is perfectly healthy and my pregnancy was great. I don't know why I'm having so much trouble after the miscarriage... Suggestions or words of inspiration?
