Permission for the pill

Hey ladies, I am 17 years old and currently have not had sex. Putting this aside every month I get horrible cramps and pains that seem to be getting worse, I also find I am quite irregular which can get very frustrating. I would like to try the pill to see if this helps. My problem is my mum, she is extremely old school and we are not close at all she would also not allow me to as she would think its for sexual reasons. Just wondering is there another way I can get a hold of them? Or ways to convince? Thank you ❤️ glad to be apart of the committee  - from Australia
