Change in stool color and consistency

Patient: Hi!I am concerned about my bowel movements.I typically dont go to the bathroom very often (once or twice a week only) and I have noticed that in the past months my feces comes out almost black a lot of the time and it never used to before..But for the past week and a half I have been going 2 to 3 times a day, with super soft (almost liquid) consistency and its orange!!I havent made any changes to my diet or been taking any medication that i dont usually take so I dont know whats going on. Should I be concerned?

Doctor:
