Go get a massage! Take so time for u, and do a spa day with frieds family or just urself, just make time for it. Im a massage therapist and Im 16w, ive worked on so many pregnant women and had work done on myself so I know the importance in getting a massage, not only can it realx u but also with help with the tension and pain we have just being pregnant. Take a deep breath and know u have cleaned every inch of the house and tell ursef " I did an amazing job, now its time for me!" but really meen it, say it a few times if u haf to. Then u can do a little light cleaning a bit just before ur due date, and it wouldnt hurt to get a room purifier that uses water for the babys room (not a humidifier, a PURIFIER, a good one is from a company called rainbow and I use it with dotera oils) that will help keep the air clean for u and baby. Hope this helps, and relax ;-)
Maybe leave your house for a bit. A change of scenery will do you good. And it will get you in a different mindset.
