Contact your MP or get the CAIPS notes to know what is the status of your file. Either they think your relationship is genuine or not, your MP should be able to get this information from the Minister as well. How they deem your status will determine what happens next.
They very well could have deemed it genuine, and your spouse is undergoing background checks currently - hard to say. Best thing to do would be to ask for a status update from the MP as that should be given within a week. Caips can take 4-6 weeks to be received.
