Any help with period pain?

I’m currently 17 turning 18 in a few months, I’ve been experiencing period pain/cramps ever since i was 11. Every month the pain gets worse. That could be because i possibly forget how bad the pain is when im off my period 🤷🏻‍♀. Anyway, every month my period lasts for 8 days which i think is normal but the cramps drag on for 4/5 days. The pain sometimes gets really bad to the point i faint. It’s become normal now for me that i throw up every period but it stops me from eating out of the fear of throwing it all up again. I’ve contacted the GP countless times, I know there are more serious problems people have and the NHS is currently understaffed but all i get is a phone call appointment and get told the same thing “take paracetamol”. Even those don’t work anymore. Has anyone got any ways to relieve period cramps, I’d really appreciate the advice, i cannot go through this for the rest of my life until menopause 🙁 and i also cant go on the pill either
