Suggest Treatment For Dysmenorrhoea

Hi doctor! I am 24 years recently married female with 5ft height and 45 kg weight. I have irregular cycles and dysmenorrhoea. Today am having very severe dysmenorrhoea with pinning sensation in my vagina and uterus esp when moving and passing urine. I have taken anti spasmodics, but doesn't seem to help. Could you please help me in getting rid of this severe pain.
