Ideal birth control?? Help a sister out

Malou
I'm a girl, 16 y/o,  never had sex but now that I've got a boyfriend, I'd like to have sex. We'd probably have sex once a week since we still live at our parents' house. Next school year, I'm going to university so we'd be having sex every few days. Should I take the pill AND condom or only use a condom?
