No reads. Could I have lost less money? What could I have done differently and why? Thanks for you help.

First of all, don't tell us you lost, it taints our opinion of the hand.

The button call/call, raise line is scary, so if there's anywhere to fold, it's the turn, but I don't think I would, especially against an unknown who may have AK here and be getting frisky.

The river is standard. You must bet that.

Sorry you lost, but it seems pretty normal from what I can tell.

It turned out the button had nothing but pocket 9's! The small blind had pocket AA. She cold called 2 bets on the turn!!! Oh well...
