Hi Angelique,
Pelvic and ligament pain is really common - specially in first time mums. There is a whole heap of stretching that needs to happen!! A good idea might be to try and look at some muscular pictures of pregnant women, so you get a better idea of what is actually going on in your body. The spine curvature and muscle separation is out of this world!!
Heat packs may help, or even try some panadol, even panadiene forte if its really bad. I went into emergency becasue of really bad pains at about 16-17 weeks, and the OB told me not to be a hero, and to take osme pain relief!! Charming huh?
Also, my osteo helped alot with pelvic pain, specially towards th end of the pregnancy. I actually had little knots in my pubic area, and she worked them all out (kinda strange while I was in there, but immense relief afterwards!!)
Good luck,
Fi
