I suspect I may have endometriosis...this is not good..what do you think of this?

Im 18 and have it and I never noticed any pain til i messed around with someone (im a virgin) but everytime I do I get paranoid and think im pregnant anywho in being paranoid I started to pay attention to my body more and I always got an odd pain in my stomach like a lingering knot. I went to the doctor and they realized I had a cyst. Noone knew I had endometriosis until the day I had surgery and I had it badddd. Tell your gyno that endometriosis isnt something to be played with and if youre really concerned tell her to check. As for the babies 70% of women who try with endometriosis have no complications. That leaves 30% who have difficulties. Youre most likely not fertile. Yet.
