Horrible back pain

Cheryl
I'm 18 weeks and in the past two days I've been having really bad back pain. I couldn't imagine how bad it would be if I were working. 
Am I the only one experiencing this??
It's my lower back and in my hips. Isn't this too early to be in pain? 
I have to stop what I'm doing and lay down and it feels like it takes 10 times as long to complete a normal task.
