You're "nesting". You're preparing your home for the arrival of the baby. It's biological, and there's nothing that you can do about it. I would suggest making a baby blanket, instead of cross stich, as that might help to satiate the inner nurturer. But with a week to go, even that might become stressful as your mind thinks; "Gotta get it done, gotta get it done".
Try to at least just stick to "light" cleaning. Take in a few deep breaths, and enjoy your clean home. In fact, take a few pictures of it. It's the last time you're going to see your home that clean for another 18 years or so.
