The pill

I'm struggling with my period lately.
My cramps get so bad I have diareea (tmi) and I'm so heavy.
I'm considering taking the pill just to maintain my well being. I'm not considering having sex any time soon. But I'm also trying to loose weight and don't want to be bloated. I've had my period for about 2years now so I expected it to get lighter but its getting worse and heavier.
Do I go to my docs or just deal with it in my own way?
