Northern Ireland's women were denied a second European Championship qualifier win in four days as Hungary snatched a 2-2 draw in Wednesday's game in Varosi.
After Saturday's shock 3-1 win over Norway, goals from Julie Nelson and Ashley Hutton put Northern Ireland 2-0 ahead after 71 minutes.
But a Hutton own goal (76) got Hungary back into the game and Szabina Talosi equalised in injury-time.
Northern Ireland are in third place in the group but have a game in hand.
Iceland lead the table with 13 points from five games.
Belgium are in second place with 10 points from five games with Northern Ireland on seven points from four games.
Former world champions Norway are in fourth place with six points from four games.
