I had SPD with my 2nd pg. Try to keep all of your movements symetrical, ie. swing both legs out of the car at the same time, get help to roll over in bed.

i recommend getting a support belt and icing the joint when it is really sore as this reduces inflamation and allows you to rest the area. when you have iced it try to keep mobile as this keeps the inflammation away longer, ie. ice it just before you go shopping and you will handle doing the shopping way better than just doing it without icing it. my physio recommended hip circles and gentle stretches and pelvic floor exercises

i would recommend getting a referral to a women's health physio as they are used to doing all sorts of exercises in this region, and an osteopath may also be helpful as the are kind of a combination of chiro and physio. I can find an article for you if you like but i think i have covered the majority of what I did. Oh and try not to do any lifting
