If the pain is very severe you can take an ultrasound scan to see if your uterus and ovaries are fine. If everything is normal you can wait, since you are young, the pain during periods may subside with time. The only treatment now may be taking painkillers during the episodes of pain. Studies have proven that banana stem and banana flower are a natural source of progesterone, incorporating them in your diet, especially during the later part of your menstrual cycle may help in reducing the pain.
