What happens if am baking bread and...?

Ok so I was trying to bake some bread this morning and I just realised the dough isnt firm enough to knead because there isnt any flour left for me to make the dough a bit more workable(AND also for the surface when I knead)Anyway so I am going to go to the shops and get more flour but will it affect the outcome since the dough will have sat without any kneading a while and then go over that process again?What if it rises without kneading(which it probably will..)Help pls, I was really hoping to make some good bread :(
