I have those sharp types of pains. mostly during my period, but Ive had them sometimes when Im not on my period. I thought it was always related to my period, but then I thought maybe its a regularity problem because I have always had a bowel movement like every 3 days. and sometimes its a hard consistency. now I drink fiber drinks and eat quite a bit more fiber and thats helped. I hardly even have them during my period or when Im not on it.
