Ways to help a painful period

Hi , I am 17 years old and I’ve been having painful periods for about 5 years now. Over the years I’ve been using many different methods to stop the pain or lower it and It never works. I tried heating pads, changing my diet , drinking more water, yoga, meditations and working out. Most regular pain medications don’t work for me and with high dose Tylenol I usually have to the take four pills at one time to actually feel some type of relief and that’s starting not to work. I also been having bad period symptoms as in nausea, diarrhea, and gas. Is there any methods you ladies have to help me with period symptoms?
