Cramps

Every time my period comes around my cramps get worst and worst. It’s gotten to the point that I can hardly walk cuz my cramps and my back hurt so much. Today I almost cried at work and wish I could leave early. My period has gotten so bad that it makes me nauseous sometimes. I never thought my period could be this bad. Why do my cramps give me back pain?

Does anyone else have this problem and is there anything that can help?
