Small blind defense gets called

Button is a loose player but quite poor and easily pushed around. My table image is taggy, for once not laggy. I sat with 50 and now have my stack having played two big pots hard. BB has only been around for a few orbits but is sat at my other tables and seems like a standard taggy player.
How do u proceed once the preflop bet is called. I was worried about BBs calling range, possibly which only two i have beat (range i thought was AK and AA/KK/QQ/JJ/TT. Could his range by wider? i made it clear that anyone who wanted to play here needed a damn good hand and bb is no donk). His turn call really scared me on a dryish board considering what i thought were his preflop calling requirements. Push the turn instead? I guess i have to call the river?
