Confused abt sex drive, just need to vent

My sex drive is low due to my birth control there’s no doubt but lately I’ve been feeling like my birth control may have failed and that I might be pregnant, which makes no sense because I take it perfectly and only messed up maybe once, not even around a day where I had sex. Could this be why I don’t like sex anymore? Because of a pregnancy scare? Has this happened to anyone else and how can I fix this? I really miss having sex but I never even want to be touched anymore
