initially i had diahrrea for two weeks , but not watery. it was brown loose stools . I ignored that since it was not everyday diahrrea. next day would be normal , then other day would be loose stools, like alternative days. other than that i had no symptoms like abdominal pain, vomiting, nausea . since i ignored this , i had one week of constipation eventhough it was a loose stool , i have to push hard for this. and i saw fresh blood in my stool for three days, but again i had no symptoms other than this. i had vomiting only once , then i took bland diets, like banana , milk, lots of fruits, activia yogurt foods that are easily digestible, since i switch to these diets, i was getting pale greenish loose stools for three days and now iam getting pale yellow stools for the past 3-4 days with small small red strings and green spots and mucous , iam not sure if that is the blood or worms. but i have no symptoms other than my pale color loose stools. what could be the reason for this . Iam just 27 year old female. is there anything i .need to worry about this , i appreciate your responses. Thanks
