By 32 weeks, I was pretty immobile. I had SPD kick in at 21 weeks and was on crutches not long after. I couldnt push a trolley or vacuum cleaner. I gave up work at 32 weeks as I was too tired and sore. We had groceries delivered or Dh bought them. I had hydrotherapy for pain relief and constant osteo, but they were only temporary.

Have you checked out the SPD thread for tips?
