It's normal, especially if you're fatigued. I'm almost 38 weeks and still haven't finished cleaning the corner of the room I need to put up the bassinet in.
I'm 25 weeks and the baby's crib is still in its box.
I think nesting is different for everyone, I've gotten things ready in stages I'm 39 weeks and just now cleaned the house but I've had my daughter's room ready since about 37 weeks
I know some women that didn't nest until right before they went into labor.
