☹ bfn again after over a year

Brandy
Period is due on the 8th took a pregnancy test this morning.. BFN! I thought I was pregnant. I just want to give up trying. My husband says if it ment to be its ment to be but after over a year of trying it brings me down every month. I want to go to the doctor to see why it's not happening but my husband says there's no need. It wil happen when it happens. By yet he doesn't realize how hard it is for me to be off bc. I have endometriosis, I'm tired of the painful cramps and migraines every month. 
I'm stuck on what to do. If you ladies were in my position what would you do? I want to get pregnant but if I can't there's no point of me having to deal with cramps and migraines every month.
