When to wash babies clothes?!

I’m almost 34 weeks and i’m not sure if baby will come early but i’m so ready to nest and feel like its not time? I bought the special laundry detergent for newborns and I wanna wash all her blankets/clothing etc before I start putting it in drawers and what not but is it too early? I dont want it to sit for weeks and need to be washed again or is that not what happens?
