TMI Question about Poop

Hi y'all! I had a bisalp on Monday morning. I've mostly been feeling great. I pooped for the first time on Tuesday afternoon, and I've pooped every day since then and haven't needed to strain much/at all since I've been taking stool softeners and drinking a lot of water. I stopped bleeding by Tuesday, but started bleeding again on Friday. It's not even enough to fill up a pad, but I am concerned because a significant portion of the blood is coming out when I poop. Is this something I should call the doctor about, or is it normal? I can't find it as a listed side effect anywhere.
