I guess it doesn't matter how long you've been married per the other people who have responded but for what it's worth we are newlyweds but we have been together for almost six years which was made very clear (with lots of proof) in our application.
If your app was received on Feb 25th, as long as all is complete and in order it looks like you should expect something in about 2 weeks since the average time has been 39 days to AOR for outland Feb applicants so far. Good luck! Hope you see it soon. It's nice to at least get that acknowledgement that they have it and are working on it.
