actually I got on this board tonight to find some answers about the very same problem, blood in stool, I am so scared its cancer. I have a app for a colonscopy on monday, it seems a long time to have to wait and worry. for you, thats your next step also, they have to take a look inside and see whats going on. another reason for blood is some medications such as anti-inflamations drugs do it to me, so thats all I know, I think there are other diseases to, like colitis and maybe even an ulcer. but no matter, you have to see the doc.
Definitely hope you both follow up on here, @cat9841 how did the colonscopy go, what were the results?
