Birth control options?

Breanna
To start things off, I have a doctor's appointment tomorrow. For the past six months every time I get my period, I have horrible cramps, like to the point where I can't walk and I've had to miss class. I'm only 20. My mom told me it's not normal to have that bad of cramps. So I made an appointment. I was going to talk to my doctor about birth control for this. Does anyone have any suggestions? Or if you're on birth control, what is it? And what are the symptoms?
