Can you buy groceries over the internet? Then they deliver to your door. Groceries are hard work.
I finished work very early so can't comment, but I understand financially you need to work, just don't work too hard when you are there!
I lounged around a lot in the last trimester as I knew I would be busy when the baby came.
I wore the SRC pregnancy shorts which helped with support in the pelvic area.
I was still going to the gym and quite energetic at 32 weeks but hurt my coccyx at 34wks so was basically out of action after that as I also had some pubic bone seperation, everyone is different.
ps I found heaps to do at home before the baby came- cooking and freezing food for after the birth, decluttering our house, baby clothes shopping, catching up with friends, etc,etc :-)
