I've suffered from back pain from about 16 weeks so have a few tricks up my sleave now:

- heat packs, especially for in bed
- warm baths
- belly belt (my physio ordered it for me)
- pregnancy yoga - I go to George St in East Freo. Brilliant
- pregnancy aqua aerobics - I go to South Care Physio at SJOG Murdoch.
- physio - South Care physio again. They specialise in pregnancy and the girls are great
- don't wear flat shoes! A slight heal is actually much better for back issues
