The timeframe is about right for late onset radiation proctitis (although can be up to 5 years)
The mucus is produced by the rectum wall to lubricate for having a dump. It's also produced if the rectum is irritated, so it's very common when having external beam radiotherapy. My oncologist refers to it as mucus farts, but the best term I heard came from someone else's oncologist, an over abundance of rectum lube. It's taken me about 15 months for the level of rectum lube to return to normal, although mucus farts were gone by 10 months.
Don't strain when having a dump, that's bad on many counts, besides not helping with the bleeding. Don't be in a rush. Take a book in with you, or do some social media on your smartphone, to give yourself time to go. That gives the rectum time to lubricate before the dump and make it easier and less likely to tear fragile blood vessels. I suspect the mucus you pass later is the mucus your rectum produced for the dump, accompanied by the blood caused in part by straining and having the dump before the rectum self-lubricated.
Having said that, don't sit on the toilet seat excessively long either, it's not great for circulation in the legs.
