Questions about endo

I’ve pretty much had all but one of the endo symptoms for some time now. I’ve gone to several different doctors, all saying “it’s a cyst” or something along those lines.. after all my test and scans would come back clean, I wouldn’t hear anything else from them. I could write a book on all the ridiculous Drs I’ve seen, but I’ll spare you☺️

Anyway, I was telling my mother-in-law about some of my problems and the frustrating drs and she texted her Dr that she loves so much. He had me call him and I told him my symptoms and he said all my symptoms point towards endo but the only way of knowing is to do the surgery. (Which he recommends I avoid)

So getting to the point here, my main concern is my fertility. I’ve read that it depends on where it grows and what stage it is. And please, I don’t want anybody on here saying “you can’t self diagnose endo” because thats not what I’m doing. But thats the only thing that makes since to me so I am going to treat it like endo until proven otherwise. What I’m wanting to know is, should I do the diagnostic surgery? Or should I just live not knowing if or at what stage it is? I’m only 18 and I think thats why Drs don’t give $h**. Any information on endo is greatly appreciated :)
