I saw a chiro all through my pregnancy with DD and it was brilliant. I have an unstable pelvis and the chiro kept it under control. I'm also sure that's why I had such a quick and easy labour, my chiro constantly made sure everything was in the right place for a good labour (gee I loved that woman ). I didn't need any x-rays at all, so it might be worth ringing a chiro and asking if they required them. My chiro costs about $40 a session.
