I can totally relate - I pretty much stay glued to the couch with a heating pad for the first couple of days of my cycle because my cramps are so bad BUT I recently tried a new essential oil blend called Dragon Time (appropriately named) from Young Living.
I tried a bunch of single oils before without much success, but this one made my cramps go away within 5 minutes. It has Fennel (I love making fennel tea for cramps too!), Marjoram, Clary Sage, Lavender, Yarrow, & Jasmine.
Also , have you read the book Woman Code? It's all about eating certain foods during certain parts of your cycle to have better periods, fertility, etc. I only tried one month of it & it seemed to help, but as a chef, it's hard for me to stick to meal plans since my meals are often leftovers from cooking for somebody else haha
