What do I do!

So I’ve been getting extremely painful periods to the point where I throw up and faint, not to mention the really bad cramps. So far I’ve been to the ER like 6 times and every single time my (male) doctor just shrugs his shoulders and tells me to take ibuprofen😤

And my mum does absolutely nothing about it, every single time I ask her to speak to my doctor about The Pill, she says she will but never does. Idk what to do I know I can’t continue to live with this pain. This year I’m in year 12 and I can’t afford to miss classes because of my period. My period comes around every month and every single time I’m in agonising pain. What do I say to my mum? She’s more into home remedies and teas and weird things she forces me to drink that NEVER works. I’ve had enough and I don’t know what to do about it, since I’m not eighteen yet I can’t book my own appointments.
