Birth control??

I'm 17 years old and have a doctors appointment next month I wanna tell my doctor that I wanna have sex with my boyfriend of 8 months. I want her to prescribe me to some birth control so I don't get pregnant and I will also be using a condom for extra protection. But I was wondering if she needs my parents permission to give that to me? Cause I don't want my mom to know she would flip but I'm trying to be safe and responsible about this and which birth control is very effective that I could use. And I also have a job so I will be paying for them. Please advice ladies!!! I don't wanna worry I wanna make sure that I don't have to worry about pregnancy!! And maybe something that gives you periods every month please and thank you☺
