Legs/hips exhausted

Kim

I’m currently 34w5d. I’ve been feeling pretty good the whole time up until a couple days ago. My legs and hips are feeling really exhausted like as if I just walked for 3 miles or something. It just started happening like over night and I’m not sure what might be causing it. When I’m feeling the discomfort, I sit down and feel much begged but then I also get sore and stiff when sitting for too long. Anyone else have this problem?
