Possible Shiny Problem

This is going to annoy some people because odds are just that way, but I've not had a shiny since the rowlet community day and I'm starting to wonder if something is up.

Usually I get a shiny every three days on average, I've an auto catcher and I play the game consistently, but for the last 12 days I haven't seen a single shiny, not in raids or research.

Has anyone else noticed a change or is my luck just low atm, to be honest 12 days isn't the longest time anyway, it just seems weird to me.

Edit: it's also worth noting I catch about 800 pokemon a day.
