I’m 29 weeks and for the last couple of weeks have been getting a horrible pain in my back after sleeping. This wakes me up after a few hours and it’s so sore I can’t stay laying down so I’m up in the small hours. It’s mainly on my right side at the bottom of my rib. It’s quite an intense ache like a really bad stitch. It goes away maybe 30 mins after standing and walking around. Has anyone else had this and if so managed to find anything that helps? Have been trying pregnancy pillow etc to no avail 
just want some sleep now
