I just tried laying on my side and it did work! Ive been on my feet alot lately i think its my bodys way of telling me to rest!
I am 34 weeks and having this also. I notice it more when the baby is sitting very low. My pain goes away when I lay down with a pillow between my knees. If your pain does not get better with rest or in certain positions then I would call your doctor. But I was told some pain is normal. Our ligaments in our hips and back are loose and the joints are separating, getting ready to fit a baby through there!
