Sharp Back pain. ( 32 weeks )

[wowiesis111]

Anyone get a sharp shooting pain in the bottom of their back ? It's not all the time and not when I'm doing any thing in particular. Yesterday was when I turned over in bed and now just as I was walking.

Never had this with ds1.
Could it just be a trapped nerve? Baby sitting in a weird position?

Keen to hear if anyone else has it as it is really quite painful.

Could be sciatica, I suffered with it pre pregnancy and have been getting the odd twinge since around 30 weeks. Particularly when I get up in the night for the loo, think it's when the baby shifts and presses against the nerve. The type of pain can catch you by surprise, it's not pleasant.
