Endometriosis?

I am trying to decide if i need to go to the doctor for my periods. They are horrible. My cramps are almost unbearable and medication does not work. It’s never regular, hurts to poop(tmi), my pelvis hurts, my legs throb for days, i bloat for no reason(i look pregnant. people notice it’s not just me), it’s bad. It makes me just lay in bed with a heating pad for most of the day and i’m a very “get things done” person. What should I do? Any idea on what to do with the pain?
