Aircraft
During approach; after selecting gear down; we received a Gear Disagree message and noticed that the nose gear indicator was not green. At approximately 1200-1500 ft; we executed a normal go-around; retracting the gear as per the normal procedure. After cleaning up the airplane; leveling off and getting vectors from Departure; we attempted to lower the landing gear and again received the Gear Disagree message. The Captain pulled out the QRH and began reading the steps. Before he could get to step 2 (Landing gear lever...Off); I noticed a change in wind noise and asked the Captain to pause the checklist a moment because I suspected the nose gear was starting to come down on its own. After about 15 seconds; we observed the green nose gear light and the Gear Disagree message extinguished. Our flight continued without incident and we were vectored back to runway XXR for a successful landing.This was the second consecutive flight for this airplane in which the nose gear did not extend causing a go-around.
B757 First Officer reported executing a go-around after the nose landing gear failed to extend. The nose gear later extended normally.
