i think you should be able to get birth control while your in high school by yourself because when i was in high school i came out and told my mother that i was having sex because i thought i was pregnant and not to mention that my bestfriend was pregnant and i thought she would be happy that i was trying to protect myself ( we were using condoms as well but i wanted to be extra sure and careful) and she told me no!!! i had to wait until i was 19 yrs old before i started taking birth control and it's the best thing that's every happened to me( i will leave the reason why out

)
