Is endo a possibility?

I have regular periods, sometimes as a teenager my periods came 2 times in a month but now they come every 28 days. They are pretty heavy I guess, I don’t soak through pads or diapers or anything because I go to the bathroom every hour to release the blood. It looks like a murder scene every time, so I think I lose a lot of blood. I definitely lose at least 1/2 a cup of blood each period if not more. My cramps are not bearable. I’ve never taken medicine for it just because I don’t like to take medicine. The heating pad helps a little but not much. It also radiates to my back bad. The other day (on day 2 of my period) it woke me up while I was sleeping in so much pain. I was tossing and turning until I finally went back to sleep. I couldn’t get up to get medicine or anything. I have to go to work and do things, I don’t have an option. I tried to play pickleball while in my period and I had to lean on my paddle in between points to make it through. I don’t throw up or anything. I do feel the back pain go through my legs too while on my period. I also get sharp lightning pains in my butt and vag area that come and go. I just don’t know if this is all normal or if endo should be brought up to my doctor.
