I just want to be pregnant!!! 😭

I feel like everyone around me are getting pregnant. Of course I am happy for them, but at the same time I just feel sad for myself. My husband is feeling down also. Whenever anyone announce that they are pregnant my husband says “when are we going to be pregnant?” “What about us?” I’m trying to stay positive, but I don’t know how much longer I can be. Losing hope.. PCOS and infertility sucks.. I feel like I’m to blame 😢 Just feeling defeated..why is it so hard..
