How old were you when you were diagnosed with endometriosis

I am 29 and had one miscarriage and one successful pregnancy so far. We started TTC #2 and I was having bad pain. I went to my OBGYN and was just diagnosed with endometriosis. I’m just curious to hear other women’s stories of when they were diagnosed. I have another appointment coming up in a few weeks and I feel overwhelmed. Any advice for someone who is newly diagnosed?
