Pulled back help!!

Brittany • Momma to a spunk 4yo boy (6/11/12) and a new little girl (5/25/16)
17 weeks and I pulled my pack organizing boxes today. I bent over to scoot a box across the floor. All of a sudden my back popped and my legs gave out. It took all I had to stand up and walk to the living room. I can't walk and put pressure on my left leg. I am uncomfortable and in pain no matter how I set. I've took Tylenol and am using a hearing pad. Any other advice ladies?
