$50+5 Is this to weak?

[Nybster]

I've been playing my way throug sng's lateley, starting at 10+1 and now I'm playing 50+5s.
My usual "strategy" in the early rounds has been to only play good starting hands (AQo+) from good position but recently I've been limping more.
This hand is one of those limps, not a perfect flop but I decided to play it anyways, lots of draws on the board so I bet the pot, however is folding to a reraise on the flop here to weak? I figured with so many limps behind me someone had flopped a set, he didn't reraise allin but just min-raised, or I was simply outkicked.
Since this was early I wasn't to happy to be moving in with TP2K, how bad was this play?

Any thoughts and comments are greatly apreciated!
