Aching on one side

Hi, anyone ever felt aching or pain at only 1 side of the body? I am having it on my left waist, lower belly and inner thigh. Only on the left side. And sometimes, I have to walk by dragging my left leg. It is hard to turn in bed too. I have to slowly hold and bring my left leg to whatever position I want it to be. I am at 38 weeks now. No contractions, baby is still active and waterbag still intact. Only lost my mucus plug last Friday, 9th Sept.
