It likely means your background check has not completed yet. Most likely it's your security clearance that has not been completed yet.
This is common. Everyone's timeline is different, even for couples.
It's not very likely that you will be asked for more information. It's not impossible, but usually such requests come sooner after the interview.
You don't need to contact IRCC. They will not be able to tell you much anyway, as the security clearance process is handled by a different agency. They'll update your case once all the results of the background check are in but this can take quite a while.
