Birth Control for mood swings

H
I'm 17. My parents want to put me on birth control due to mood swings I supposedly gain while I'm on my period however my periods are normal 6 days and are fairly light compaired to how they used to be...they are making this a huge deal...I'm not having sex and I see no need to take it but they are still making me go to see the OBGYN who is someone they know...I just feel invaded and insulted. What should I do?
