Adjustment of Status - I-485

hello guys ,
i'm writing yet another post hopefully someone can help me out , I've had my interview yesterday the officer was very nice and young he didn't ask that many questions besides the basics , he did not separate us and i believe we did well it lasted about 15 minutes at the end of the interview he told my husband and i that he was going to recommend our case for approval and that we should receive my green card in the mail anywhere between 2-4 weeks he gave us a sheet and he explained its marked under review but that hes going to recommend approval to his supervisor. However my case status remains at "interview has been scheduled" and Ive noticed in this forum that people that have had their interviews in Newark usually get their status updated right away, does this mean that i got denied? do the officers just say they're going to approve a case or do the sometimes deny people straight after the interview please someone help feel so stressed out ! or has this happened to any other filer in Newark ?????????? PLEASE HELP!!!
