Can the nesting just kick in already??

3 weeks away from due date. I keep starting to get things organised and cleaned because I know it needs to be done, but I only ever get part way through before I just want to throw everything out and burn it all. I have no desire to do all this. With my first, my house was blitzed from top to bottom when I was 36 weeks. Even my damn floors were practically sparkling. This time I can barely be bothered to do my laundry...
