I'm out and want to give up....

This TTC can be disappointing and even depressing. AF came today and I'm out. I have this horrible feeling. I just want a baby. We did everything we could to try and nothing. My husband is support but I still feel like I did something wrong 😕 like maybe read and OKP wrong or something. It's making me feel really down. I just really wish I was pregnant. It's making me just want to give up altogether.
