My periods are getting more painful from last 7-8 months. Its pains very much on my lower back and area below my navel. Even sometimes my legs feel very weak. My mood goes very irritating and sad too. These all things doesnt used to happen before but know i am facing these problems. My body lacks in blood but thats my birth problem. During the periods when it pains i feel like something is intereputing in between. The pain starts and it rises for few seconds and then it goes away. I am taking some home remedies but they are not helping much !
