Help mehhh

Do I specifically need a parent to get a prescription for a pill, or can I use another adult. Because my mum definitely wouldn't let me get the pill because I'm almost 16 and my sister who is 17 only just got the pill. But we've both been dating our boyfriends for almost 6 months. And it's just so hard that always have a condom on hand an my mum would make me break up with my boyfriend. I have no idea hat to do these days.
