Struggling a lot

I’m jealous of everyone who is expecting. Of course I’m happy for people who are pregnant but I’m freaking angry. My period is late and all tests are negative so pretty sure my cycle is just screwed up. Awesome just another thing going on! I already have a long cycle and get less chances than most women. I’m so frustrated! I don’t know what to do with these emotions. My anger is profound. I’m angry that my baby died. My SO never wants to be intimate and I stopped asking him because he always says no...and when he says yes he can’t finish. I feel lost. I should just give up.
