Infertility

My husband and I have been trying for 8 months I’m 35 he’s 40 he already has 4 kids I have none... I found out I have a border line egg count and have a polyp I need removed from my uterus... we are seeeing a fertility specialist next month but going through all this is the hardest thing every month I think this is it and I get my period and fall apart and my husband doesn’t get how hard it is for me I feel like a failure I see ppl who have kids and don’t try and don’t care to even have kids and others have to struggle when they would give anything to be a mom
