Any body get these, it really hurts when i sit down, just a sharp shock pain stright across then goes.

I think that's to do with the bones having to sort of move?

I have this, too. It's caused by the hormone relaxin, which loosens the ligaments in the hip and groin area... Some women also suffer from recurring hip-dislocation because of this during pregnancy. If it gets really bad as you grow, your midwife may refer you to see a physiotherapist who can give you a 'femibrace', which will take the pressure of your growing bump away from your legs and back and hold you all in place.

Good luck, I hope you don't get the pain for too long!

I've had really similar pains too, although they're not really pains more like a stitch down one side. It only aches towards evening time???? I've been told by people that it's growing pains and I also read about that pelvic pain.
I'm sure it's nothing to worry about. (We're also due around the same time so maybe it's a 13 week thing?)
