Asking to going onto the pill?

Alysha
Hi, 
So I am 20 and want to ask my doctor to go on pill for many reasons. The thing is my doctors surgery my hole family go to and I don't want my mum and dads doctors to look it up and tell them I am on it. Also I just feel scared to asked him as he is a male but I have b12 issues do don't know if this would affect being on the pill?!
Advice please?
