Endometriosis

So I just found out that it is very possible that I have endometriosis. Feel free to talk about how it feels for you if you have endometriosis, I just want to make sure I’m not alone with how I’m feeling. Every 4 months or so I get this extreme pain in my stomach to the point where I have to lay on the floor it hurts so bad. I’ve seen many doctors as most of the answers I get is that it’s probably just period pain up until September when ( this is probably tmi) I had an episode and about 3 hours after a chunk of flesh fell out. Negative pregnancy tests and all. Give me your feedback if you feel up to sharing. ❤️ thanks for your time
