Will my gyno know if I have ever had..?

Will my dr/gyno know if I have endometriosis or ever had pelvic inflammatory disease? Going for hsg tomorrow for my own peace of mind, 21, never really tried to conceive with my fiance of 2.5 years. Found out i had pco (pcos minus symptoms, reg periods) two years ago with a trans l ultrasound. Lately fertility is playing on my mind so i pushed for a hsg, going tomorrow for it, been reading and found out that endometriosis and PID can be a cause of blocked tubes, would I know if I have this through my gyno? I know I have never had an sti. Thanks.
