Birth control

Patient: Hi im rachel and i was wondering if the ‘pill’ is free im 15 at the moment and having protected sex but there’s always a chance of something going wrong. if something did i wouldn’t be able to afford an abortion and my parents would die if they found out. so hiding it from parents, dealing with the father ect. would become very depressing so i really want to avoid all of that and keep my parents out of it completely. so my question is,,, is the pill free? do i need parent consent to get a supply of it? how do i get it? what confidentiality do i have if i see a doctor ? thanks for your help
