HELP! Is this normal? (Poop/TMI)

My breastfed 3 month old has been having mucousy /runny poop for a week now. Occasionally there is a diaper with more greenish poop, but usually yellow/orangish. She has 3~5 poo diapers a day, which is not an unusually high number for her. (4~6 pee diapers a day too) Doctor said to give her pedialyte if there is dehydration. But she doesn't seem to have dehydration signs. Now I've come to the point where I am not sure whether her poop is normal or not any more...Anybody may have some experience in this?
