I had two toddlers when I was pregnant with the twins and TBH I just ignored the housework, or asked friends to help when they were visiting. Things like picking up toys off the floor can be done just once a day, cleaning the toilet is possible with pelvic pain (at least it was for me) but cleaning the bath was not to I left that to OH. I did all the dishes in the sink rather than use a low down dishwasher, but if you do that remember to sway from one foot to the other rather than put all your weight down one side.

Honestly it is awful to live in a messy house, but it is much worse if you put your pelvis out even more. There were times I needed a wheelchair and trust me, that is not fun. So take any help you are offered and try not to put yourself under too much pressure.
