I think if that happened to me where I have a credit card, my first step would be to contact that institution and politely ask "what the heck?" If nothing else, that records your concern over the matter (in case something fishy did/does in fact happen). If the institution's response is "what's the big deal?" or the like, I would think twice about retaining them as my credit card supplier. Oddball thought that just occurred to me: was it 47 past the hour when you did log in today? Could a time zone difference account for the weirdness? I realize probably not, but I did call it an oddball thought. Sorry, I realize none of my post will probably ease your fear.
