The image following shows which sites were vulnerable to the Heartbleed bug and which ones you should probably change your password for. The thing that is a bit shocking to me is that Facebook, Amazon, Google and Yahoo were all affected.
Now the fact that these sites had some vulnerability doesn’t mean you have already had all of your information stolen, it just means that it is a possibility that they could have gotten some of your data, specifically your email address and password.
I’ve personally changed my password on some of my accounts so far and will continue to do so, I’m really glad the online banking wasn’t affected.
