Pain on period

I have been off my birth control for over 4 months now. My periods are 10 times worse every-time I get ready to start or the week I’m on my period I swear I’m in the worst pain and always extremely bloated I look 6 months pregnant. (I’m very time also) my cramps are 100 times worse lower back pain and always get horrible diarrhea. What can help me get through it? I’m not getting back on my birth control because it was causing many other problems. But I find that being off my pill my periods are 100 times worse . Any idea how to solve the problem other than getting back on the pill? Home remedies or any suggestions?
