Sciatic nerve pain

Is anyone else dealing with this??? I'm only 10 weeks but I have this terribly pinching pain in my right butt cheek. I'm only assuming it's my sciatic nerve because it defiantly fits the description. It hurts so bad when I bend over or squat down. I don't know how I'm going to deal with this, especially at work. I'm a hair stylist so I'm constantly on my feet and bending to wax and shampoo people (which is so painful now!!)
