Birth control, partners fertility problems..

I've never taken any form of birth control before. I have a very regular period that kills me every month! I don't need it to prevent pregnancy because unfortunately my Partner can't reproduce, don't feel bad we're very happy! I was wanting to know what would be good birth control that's not an iud or depo. I'm very skittish when it comes to placing objects into my body for long periods of time. Is there something out there that would help lighten my period and my terrible cramps?

Any positive feedback would help! I need an idea of what I want to talk to my doctor with!
