did i play this correctly??

I have been lurking around for a while and this is my first post. I do not have the hand history with me at work so this just off the top of my head, sorry.

Poker Stars $5 stt, blinds are 25/50 and will be going up to 50/100 next hand. I am the small stack with about t1200, 6 other players, 3 big stacks, the other stacks have between 100-500 more chips than me.

I am UTG and dealt QQ, I bet 400 with the intention of going all in with any flop, I get 2 callers. Flop is 2 4 10 rainbow and I push.

Right call? Should have I pushed PF?
