Endometriosis

Hey guys so this time last year I got a cyst I was in agony for 7 weeks before It burst and that was that no more pain and been fine for a year then we started trying for our second 3 weeks ago and I got the horrid cyst pain again. Constant ache in right pelvis side and hurt to hell when I ovulated for 2-3 days its just niggling now. I have just had a scan today and there was no cyst and he mentioned possible endometriosis and the only way to tell is through a camera. At the moment that is my last option as I had surgery to have appendic removed 5 years ago and it was awful experience infection after infection needed a drain to.

Does this sound like endo as it's only been 3 weeks and I dont have massively heavy periods or horrendous period pains just the typical
