Period Cramps not Normal?

I get excruciating cramps the first few days of my cycle. I take extra strength midol, but after two hours the pain comes back... Almost like someone knocked the wind out of me and I can't think, breathe, or relax my muscles. I don't want to take midol every two hours for 3 days straight. It's honestly like nothing I've ever experienced. I got my implanon removed 2 months ago and hoping it would help but it didn't. I don't have insurance so I don't really know what to do. I know something is wrong but I can't afford a doctor or medication. I'm not looking for advice I guess, just really struggling with pain. I just wish I knew what was wrong so I could try to fix it. *Cry*
