You might want to try asking about an IUD! Though, they actually made mine heavier (like, a LOT heavier), you don't have to take anything and there are no hormones to mess with your body.

And I don't know if it's anecdotal or what, but I've had shorter cycles and less cramps since I switched to cloth pads. I use these ones: http://partypantspads.com/ I'm not the only one who reports that, so who knows!
