Sex drive and birth control pills

I stopped taking birth control pills back in December and went back to using condoms. I noticed that during and after and currently still, my sex drive has plummeted. Has anyone else experienced this? It's frustrating to me because I really enjoy love making with my boyfriend, it's the best I've ever had. But within the past year I just have very little drive. It's nothing to do with us or emotions, it's just purely because I just don't feel the urge often anymore.
