Blood in Semen after Prostate Biopsy

I couldn't find an existing thread on this topic, but I wanted to share what I'm seeing so far, and compare with other's results.

I'm 58 years old. After discovering a 5+ PSA result in a routine adult physical, I was scheduled for and received both a MRI, and a Transperineal biopsy. In my case, they took 16 samples. I do not yet have the pathology results.

I was told there could possibly be some blood in my urine, but to watch for clotting, etc and large amounts. I was also told there would likely be some blood in my ejaculate, tapering off over time. I understand the amount of blood can be influenced by number and location of samples.

I was not prepared for what happened though. Four days after the biopsy, and to my horror, I found my expectations were way underestimated. It was not "streaks or spots" of blood, nor was it red-tinted. It looked to be pure blood. The volume was probably double what I would have expected. Hoping that the next day would be more normal, I again tested the waters.. It was nearly as bad, however, the color seemed to be a cross between pure blood and fresh motor oil.

I've got a message into my care team, and I'm awaiting a response while I also await pathology. I'm a bit nervous.

Has this been other's experience? If it is common, why understate it in the publications I was provided?

I have not noticed blood in my urine, however, it tends to be dark-ish as I tend to under-hydrate.
