HI, I'm a 22 year blood female that found a little bit of blood in my diarrhea, however I'm also on my period could it be just period blood? Because when I wiped there was blood on the paper but when I wiped inside the front there was no blood. So should I worry? Side noted the diarrhea started after I ate some homemade pasta and potato with eggs, I'm scared I read the symptoms for colon cancer and I don't know what to think.
