NL4 AKs float flop or fold?

Hello

Here I'm in position with AKs. Standard 5BB raise preflop vs UTG limper. Both blinds call and limper folds. I was going to check for free turn but the BB (30/5) donks into me. Offering pot odds of 3.91:1 I call with my two overs and back door flush draw figuring I have implied odds to make up the difference if I hit, and if any high card comes I can probably represent it if BB gets scared and checks.

Is this an okay call or a mistake?
