32 1/2 wks, no braxton hicks? but weird pelvis pain, twinges?

32 1/2 wks pregnant, but i havent been noticing or feeling any braxton hicks contractions at all. the baby moves alot, so i know that he is ok. i have been having increased shooting-like pain around pubic bone area, and groin achiness and a stretching-feeling. should i be getting braxton hicks yet, or...? what's the deal.
