Well on 2/15 my WMR status said "return still processing"and then when we had the next update my WMR status said "being processed". I was told that still processing meant your return is still being processed.....and if it says your return say it is being processed that your return is complete and awaiting approval. I wouldn't worry too much unless I receive a letter or it's been longer than 21 days or you've been given a tax topic and I have none.
