Handling cramps at a young age 😭

I am 14, my period started in August and I’ve had one about every month but until the last few I’ve been getting horrible cramps. I’ve tried heat packs, putting my legs up, and just relaxing but none of them worked. It’s to the point now where I’m worried about going to school the next day because I can’t just lay down there. Will cramps subsided as I get older? Or will they worsen? Is there anything I can do to relieve the pain? Thanks ❤️❤️
