National D Visa for travel to other Schengen countries


My National D visa (multiple entry) will expire next year on January 31 and I have stayed 12 days in a Schengen country. I am still waiting for the result of my temporary residence permit. I would like to know if I can still spend another 6 days in another Schengen country this December? Anyone has the same experience regarding this and some border control issues?

Thank you so much for your help.

Best regards,
