yes - turns out my pelvis was out of place, as yet another left over from my last birth ...

but I've been seeing a chiro, who is sorting it out quite well.

if you can, find a chiro who is very experienced in treating pregnant women, and they hopefully will be able to help you too

and I now sleep on my left side with a pillow under my belly, and another pillow under my shins/feet (rather than between my knees) and it's helping me
