Birth Control & Parental Consent

Lexie • 20 years old, biology major and aspiring ob/gyn ❤️
I'm on the depo shot right now and I hate it. I just got my second shot today. It's made my hair fall out, my sex drive has gone down, and my periods were up to a month and a half long. I talked to my mom about the implant and at first she was iffy, but now she won't at all. She thinks it'll make me infertile because it 'happened to her friend so too happen to me'. Anytime I try to talk to her about it she just interrupts me and doesn't let me speak. I'm not saying I'm super irresponsible but I can't keep up with a pill everyday. Any other kind of birth control I'm
just not comfortable with. Would my gynecologist let me get it even if she says no? I mean, a 14 year old can go to planned parenthood and get birth control pills without their parents knowing and anyone can get an
abortion without their parents knowing, so if my mom knows but just doesn't agree, could I still get the implant? I'm 15 & in 10th grade and have been in the same relationship for about a year now
