Sharp Pains

I've been experiencing sharp pains in various areas of my abdomen and sharp shooting pains go up my stomach. I am not sure if this is something that I should be concerned about. I do not believe that I am pregnant, because I have been getting my AF. I have also been experiencing back pain more often than usual. At times I experience pain while I am having intercourse. Does anyone know what this could be? Should I be worried? It's been going on for a couple of months.
