Hi
Well there is no way to check on a IV case. IV case mean your case now either your loacal embassy or some where immigratoin office. So if your case is in embassy you may just call them and can ask them about your case. Mostly they say your case are pending due to name check something like that. But you must ask them time by time. If your husebend name are a common name then it may be take a few months. there are many people who are waiting their interview call for several years but they are stuck on name check list.
Hope you will have good news soon.
