Birth control: the pill

Jamie
So I'm 18 about to be 19 and I've never had to use birth control because of abstinence but getting older and Also have been with my boyfriend (we plan on waiting till marriage), I plan on going on the pill (no harm in precautions) but no matter where I try to find information about it it's always so incognito and if I ask my parents (with are Asian) they'll start accusing me of having sex because if I'm not having sex then why would I need to go on birth control. Please help me with how to get the pill and do's and don't for future reference.
