No Sex Drive

Saya
When I'm on birth control, my sex drive goes down to an absolute zero. And then when the one week comes around to either not take any pills or take the placebo-like pills, I get my sex drive back. It works like this every month...it's like clock work. I've tried one other kind of birth control pill, but it hasn't changed anything. Has anyone experienced something like this and have any suggestions? I'd like to get this fixed if at all possible :)
