Endometriosis

I haven’t been able to get an appt yet with the doctor my best friend sees(she has PCOS and says he’s wonderful). I’ve had a hunch for a while that I may have it and seeing how I haven’t gotten pregnant in the past 4 years, it really worries me. Me and my SO aren’t actively TTC but aren’t preventing either, we just go with the flow. I have two daughters from a previous marriage, ages 8 and 5. We both want kids and I’m so worried it won’t be happening. Do any of you other ladies have Endo? And could help me out with more information?
