You need to look up your gravity readings. See if you were on target. OG and FG are pretty crucial numbers. Like others have said before. I'm leaning on the fact your beer wasn't quite finished before you bottled it. OR you went a little heavy priming sugar.
Either way, I'd keep it chilled and drink it up. If it gets warm you may pop a few bottles. Been there done that... LOL
But too much head...its never a truly bad thing is it?
