Minor being forced to birth control?

can a minor refuse to take the birth control
its the shot and it messes your body up bad
i tried telling my mom and doctor that i didnt want it but ive still had two shots of it

is it legal for me to refuse that form of medicine
and can my doctor tell my mother if i opt not to get it
legally?
Update: its a health reason i want to have kids eventually i was sexually active but it was with one person and we both got checked before and after the intercourse and used protection
Update 2: thank you so much; the only thing is my doctor tells my mom everything but really if i refuse and she throws a fit or the doctor tells her i could go before a judge and it be counted as child abuse of some sort?
