Thanks for the query
From what you are describing it definitely sounds like blood and mucous filled blood. However in order to know for sure you will have to give your stool sample to the laboratory for stool routine and stool for occult blood. You are on the right medications and lifestyle modification and I suggest you continue them.
I strongly suggest you not to ignore this further and visit a gastroenterologist for further work up including endoscopy
I hope I was of help
