Does anyone else feel like their pelvis is being pulled apart like a wishbone?

I had this pain with my first pregnancy and it started sooner/more intense this time. I'm 28 weeks now. The best way to describe is I feel like my legs are being pulled apart from my pelvis. It's so sore all the time. Sitting too long hurts, standing too long hurts my lower back, walking too long hurts and laying too long makes my sciatica flair up.
