Hate that my body doesn’t work anymore :(

I was so blessed 6 years ago with my beautiful little boy, I love him with every fibre. But I can’t help longing for another... I see people posting pregnancies and am genuinely so happy for them, but every time the pang of hate for my body deepens. I was diagnosed with PCOS two years after having my DS and we have been trying ever since. I’m sure some of you share my feelings of utter uselessness on not being able to conceive another and the awful tricks your body plays by AF not showing up. Every time I take a test I have hope that maybe this time two lines will appear but it’s always crushed :( I haven’t had a period yet this month but I don’t want another negative so I’m refusing to take a test. Sorry for the long post I’m just feeling incredibly sad about the whole situation at the moment :(
