I wouldn't worry too muchover two weeks...
What are the temperatures in the cage? It could be cool, as well as shedding soon. Try placing the snake in a small container overnight with the pinkie mouse. DON'T PEEK! Often works wonders on non feeders. There are a slew of tricks to try (tease-feeding, lizard scenting, trying live, braining, etc.) but I don't resort to them until the snake is willing to have a slumber party with it's normal food item in a deli cup.
Good luck.
