Difference between endometriosis and dysmenorrhea?

I’m seing a gynecologist this month and am not looking for an online diagnosis. However, I’m just curious to what the main differences are between endometriosis and dysmenorrhea? I have really painful mentrual cramps and some additional endo symptoms like pain during ovulation/in thighs/lower back etc. but my symptoms seem like nothing comparing to my two friends that have diagnosed endometriosis (heeeavy bleeding (mine is so light), cramps for days (I have terrible debilitating cramps ”only” for 1.5 days) etc.). I am worried I will go in to the doctor claiming I have endo & place all my hope for an explanation to my pains in endo when ”all I have” is terrible, but less severe than others, pains throughout my cycle. Again, I’m not looking for a diagnosis online, but wondering if there are certain ”criterias” to endometriosis that go beyond my symptoms? Has anyone here been diagnosed with endometriosis with ”less/lighter” symptoms than the ”mainstream” endometriosis patient has/what is usually described online? Thanks!
