Aww honey It sure does sound a lot like SPD to me, but don't be surprised if your OB knows stuff all about it, I've found most OB's and even midwives are a bit clueless about the condition - either a physio or a chiro will be your best friend at this point. Mine is just starting to kick in now, I found in most of my pregnancies that to roll over in bed I have to be supporting both sides of my hips and I kinda flip myself over - like a whale would I imagine!! I've also been known to wake DH up and ask him to roll me over so I can support my pelvis while doing so. Definitely no standing on one leg, keep your knees together as much as you can and support your pelvis with a belt of some type. And ice it of a night time
