Just wondering if anyone else is / has experienced this and what it was.....

I am now 32 weeks (Oh my gosh!!) and am starting to get the pain in the groin area.

Now i realise this is pretty common..... but......

When I sleep at night I sleep on either side - and when I roll from one side to the other it hurst - really hurts - in the pelvis, and as i turn there is defiantley an audible "click" down there (DH has heard it too).

Is this common / normal? Its as though i can feel my pelvis re-alligning and its damn uncomfortable............
