Processing EAD and i 485 these days is slow dude, not only for you . i believe for everyday. Your fignerprint was on Jan 30, mine was completed on Dec 4. I filled 585 and EAD on 1st week of November 2018. Case was transsfered to St Loiuis , national benefit center at the end of Jan2019. No update then. Just waiting and waiting.

have patience, u will be good..
