Folks with endo, what are your symptoms?

I had talked to a friend (who had endo) a while back and she said that I might have it. Now, I feel like I am just overreacting but I want to hear about symptoms/experiences of others. I have been on oral birth control for a few years and all the symptoms that I had before I went on oral birth control have been slowly been coming back since I’ve been on the same prescription for 3 years. Before I had severe cramps (like curled on the floor pain), nausea, diarrhea, and medium pain during a bowel movement. The cramping hasn’t been as bad but is slowly getting worse and it hurts to poop (I’m sorry super tmi).
