Endometriosis question

Katrina
My husband and I just started TTC about 3 months ago. I see a lot of people on here say they have endometriosis. I don't have this, but I had a question about it. I go to the gynecologist yearly for Pap smear and check up. If I had endometriosis, wouldn't the doctor have told me at these visits? Or would I have to make a different type of appointment to check for this? Again, I don't think I have it, but just curious about it in case I need to get it checked out.
