Should I????

My mother wants me to go on birth control because she fears I may become pregnant. I don't really have sex (only like once every few months). When I do have sex we use a condom and the pull out method.  My period is already really easy to track and it's extra light and only lasts 2 to 3 days.... I haven't had a pregnancy scare at all. I am just not sure if I should take the birth control. Please help... Thank you.
