So Ive been worrying almost non stop about this from this morning. A week or so ago, I kept having diarrhea with a little blood in it. Then it just stopped and went back to normal. This morning it happened again. There were two stools in the loo, one was half grey half the normal colour and the other had reddish lines, looked like fresh blood. I have been panicking a bit. Although I did have red pepper yesterday, so I dont know if that was to do with it. I have also noticed that my poop was the colour of cardboard (that sort of greyish brownish mushy things). I have had a stressful time with a new job (long hours, long commute) and eating little and often and "on the go" so I think it might be that. I want to take my omeprazole regularly now just incase it was a stomach ulcer or something, anything have anything similiar?
