Birth Control

Lala
I have severe breast pain about a week or two before my period and it is very painful, I start bloating and I have no energy to do anything. I get a lot of acne and I get very emotional and cramps are excruciating.
Should I talk to my doctor about getting on birth control?  Anyone on it for the same reason? I'm on cycle day 20 and I feel the symptoms coming. I'm 15 and I don't want my mom getting the wrong idea, I'm also sexually active with my boyfriend of two years and it would be a great option for the both of us. Any opinions and suggestions?  If I want to get on it how do I without her finding out?
