I think after two risings, your yeast is fairly well expended. I would dissolve another packet of yeast in about 1/2 cup of lukewarm water, once the yeast has bloomed, stir it into your dough, cover and put in the fridge. On Saturday, take it out of the fridge, divide it in half or whatever you were going to do, kneading enough flour back in to each piece to make a silky dough. Let it rest and then form into what you are making. Only let it rise once.
