To put it bluntly, if you have to ask if a nonfeeding hognose is normal then you did not do enough research before buying it. You cannot talk about a captive hognose without mentioning these animals going off feed. It is a fact of life with these snakes and something you should be well prepared for.
With that in mind I have a few suggestions. The hot side may be a little too hot, especially in such a small container. Try cooling it down to 85 at the maximum. It is also not a good idea to feed your snake in its container where it can swallow its substrate. With an animal so small it would not take much to cause an impaction.
It has not even been a month since the last time it ate, and also keep in mind it is the middle of winter. Your best chances are going to be using a frog scented pinkie in a dedicated feeding container. For more feeding tips look below…

"The rattlesnake may be esteemed an emblem of vigilance. She never begins an attack, or, when once engaged, never surrenders. She is therefore an emblem of magnanimity & true courage. She never wounds until she has generously given notice even to her enemy, and cautioned against the danger of treading upon her."
-- Pennsylvania Journal, December 1775
