Period changes

So I usually have very regular periods with little cramping, but lately I have been cramping more and more. My body gets really hot like I have a fever, my ovaries feel like they're on fire and need to be cut out, I bleed ten times heavier on days 1-3 but then thin out like crazy, and I think I've been getting migraines. Usually I just sleep it off, eat a lot, and stay in my room, but with being in college it's hard to do that because I'm busy. Would it be advisable to get on birth control to take control of my symptoms? I'm really scared of birth control though, because I don't want the chemicals messing with my body and messing up my chances of conceiving later. Really lost here...
