villain appears reggy, tiny sample

Since the board probably hit my range better than his and I flopped ok equity, I decided to bet planning to keep betting on a lot of turns cause his hand should mostly be capped to overpairs.

I was unsure whether or not to continue here though. The 4 is a brick, brings another FD which he might have turned or renders my perceived range more drawheavy and he might even c/shove which is kinda unlikely but would nevertheless suck hard. So should I continue betting here or check back and take my equity, possibly bluff some rivers?
