Endo?

What symptoms did you present to your doctor before you were diagnosed with endometriosis? I have very, very painful periods to the point where it's hard to function most days and always need some sort of pain medication during that time. I also pass a lot of huge clots while on my period as well. 
Sometimes I'll experience pain during sex too, like a cramping pain in my ovaries. Back pain and fatigue are a constant, but I also have depression which contributes to the exhaustion. Would just like to hear some feedback from you ladies. Thanks.
