I’m so worn out I don’t think I can do this

Going on 7+ years of trying with no baby any where in sight. Doctors don’t know why it hasn’t happened yet... my tube (lost one to ectopic pregnancy) had been checked and it’s open doctor doesn’t see that being our issue,. Husbands sperm quality isn’t perfect but it isn’t horrible. My whole problem is I want to keep trying but at the same time my periods are excruciating painful. I’m on my knees crying and holding back my painful screams every month. I want to be done trying so I can work on my endo management but I also want our baby.... why can’t this just happen for us?!
