At this point I would give your beer a swirl. This will get yeast that has settled back into suspension. Can you post your recipe? Some brands so extract (I am assuming this is extract) are less fermentable than others, and it is possible that you are at final gravity, although highly improbable. However, if you are getting the same reading two days in a row, the yeast are not munching on that last bit of sugar very fast. Give it a swirl and then give it 24 hours. See if it has gone down any.
