After defecating, had bright red bleeding, with bright red clots with body tissue. I had no problem with defecating.

Probably OK. It may be a little tear in your anus. Are you feces hard? Probably nothing to worry about unless it happens again soon.
Thrombosed hemorrhoi. Could be a thrombosed hemorrhoid if you felt a mass around the anus. Could be internal bleeding but quite unlikely. I would wait 1-2 days and if it gets worse then get it checked out.
