My fiancé had an interview early Feb and right after that the CEAC status changed to "Refused" as she was asked to mail in additional document. We found out today that our case was approved(Hooray!) at the consular level, and we are currently awaiting her passport to be delivered. Our current CEAC status is exactly the same wording Barbara shared, NONIMMIGRANT VISA APPLICATION. - APPROVED. What's interesting is that altho it displays as NONIMMIGRANT, we still need to select IMMIGRANT visa type on the CEAC website.
It might not be usual to have a second or multiple interviews, but I saw some couple from India had a second interview and got approved later. So I hope your case could be resolved soon too. I totally understand it's nerve-wrecking, but just hang in there, your patience will be rewarded eventually.
