low sex drive

So I have a problem. My lady bits have no desire to have sex. I don't care how much porn I watch how much foreplay goes on my lady bits just don't cooperate. I just turned 19 yesterday so age isn't a problem. The only thing I could think is causing this is my birth control. I take the Levora 28's. Does anyone else have this problem any suggestions on how to fix it? I miss having sex and I know my so is suffering too please HELP!
