I am a 24 year old female, 5'2, 190 pounds. I am recently experiencing short, thinner and slightly flattened stools. No pain and no blood, but I do seem to have to try harder to expel my stools than usual. I do get the feeling that I can't empty completely. I have no family history of colon cancer that I am aware of. Does anyone have any idea what could be the issue? I have made a doctor's appointment for the end of the week but am wondering if I should wait or try to get in earlier. I am a worry wart and this isn't helping! Thanks!
