We know that a chasson is not permitted to do work during his Sheva Brachos. Two reasons: Either because he must spend the time bringing joy to his wife or because he is compared to a king and a king doesn't work (See Evan HaEzer Siman 64.)
I once heard there is a discussion in the poskim if a kallah is not allowed to work. Although seemingly according to the 2 reasons stated above this wouldn't apply to a kallah still I'm curious to know if the poskim discuss this in any way and give reasoning for either side. In particular I've heard there is a Maharsham about this.
