I feel bad 😩

My mom thinks I been taking my birth control pills but I haven't because I want to have a baby but she doesn't that. So now When she asks me about me taking them I just Tell her Yeah but I really haven't I just throw them in the garbage. I feel Bad but it's my body and I already know the consequences. And I think I'm pregnant my period is now 7 days late I'm not a little kid I'll be 21 soon so..
