Ugh. I had this the last time around too but forgot how sleep-disturbing it is! I'm having to flip like a pancake from one side to the other all night as I'm waking up and finding my hip has gone to sleep or is very sore.
At the mo I'm sleeping with a pillow from my knees to ankles but it's not making a huge difference I don't think. Just makes me irritated when I'm trying to turn over with a pillow between my knees!!
Anyone found a solution to this type of hip pain? Please share!
