I'm 15 years old and have never had sex before. I've been in a relationship with my boyfriend since March and want to go on the pill to regulate my period, considering I've skipped it for six months before. My period is usually 5-15 days late and extremely heavy. Knowing I have a boyfriend and are at the age a lot of girls start having sex how do I ask my mom for birth control without her thinking I want to have sex?
