What did I ever do wrong to deserve this....

Well to put this simply I feel like a piece of shit. I can't get pregnant. I feel like I am a big let down. Everyone in my family has had children perfectly fine. My husbands sperm is exceptionally good. It's me. Everything is wrong with me. I just want to scream and break down. I feel like I just want to shake my uterus and tell it to wake up! This is my ninth trying. I just give up....I hate this. Never though trying to get pregnant would be this hard....and to think I once wanted to have 4 kids when I can't even make one hahaha...jokes on me....
