Frequently changing bowel habits

Hello,

I've been dealing with some strange bowel habits over the last few months. I've seen everything from diarrhea to black stool. initially believed I was dealing with hemorrhoids as I did December of 2017, but current symptoms are alot different that what I was had experienced then. I normally would have a few bowel movements a day, but this has slown down to one a day or more due to the fact that I feel as if I can never finish going. My diet has also slown down, only eating once or twice a day, while becoming full very quickly. My symptoms are worrying me and are giving me the impression of a blockage, as I may not have a BM one day, but digestive sounds are very prevalent. I've noticed rust colored stool often & if not there may be small sections that give off a reddish hue. Gas has become hard to pass & BMs vary from thin & narrow to sausage but jagged and broken. I have an appointment with my PCP in about 2 weeks, but I'm wondering if time is of the essence in my current situation. I've attached photos of my BM's and other irregularities. Thank you in advance for all feedback!!
