My Period Hurts Really Bad!!! im only 15 and it last for two -three weeks at a time.?

I tried taking ibuprofen, tylenol, but it doesn't help i hate this. I would like to hear the male and female side of the answers. I feel as if im going to just die from all this pain. IT HURTS REALLY BACK IT FELLS LIKE UR CONSTANTLY GETTING STABBED IN UR LOWER BACK AND STOMACH. I start to feel very sick with pain and i have a very heavy flow. I use a tampon and a pad to soak up the blood. I feel sick and irritated. It is the worst i have ever felt. I Need Help!
