Bc pill

Next month I have an appointment to get a pap smear for the first time. At what point do I bring on wanting to get on the pill?(I'm 20) I want to get on it because I'm sexually active, not for my period or anything.

Like do they talk to you and stuff and ask if you have any questions before they start or what? Super nervous about the whole thing really. I'm going to write down all my questions, but still.

And if you think you have an infection like bv do you have to straight up say i think I have an infection or will they figure that out themselves? I am wondering about so many things but I dont feel comfortable talking to my sister and my mom wouldn't know anymore than I do since she hasn't gone in years and is less educated on female health than I am
