Change in libido?

Ok, so I used to have the sex drive of a bunny in heat. I always wanted it, it was always on my mind and I would be down for round two before round one was over. When I got engaged, I got on the pill. It killed my sex drive. I mean, screeching halt. Sex became painful, even with lube. I was only on the pill for a year. I've been off it three months and my sex drive still hasn't come back. I'm worried because I know my husband wants to have sex a lot more, but I'm just never in the mood anymore. Has this happened to anyone else?
