could be ligament pain or just your hips spreading preparing for labor. I have been having pelvic pain since 24 wks. and ligament pain. keep track to make sure they aren't contractions.
As long as you aren't having consistent contractions it's normal. Your 32 weeks chances are baby has dropped and is in position and that's likely why you are feeling that! If your concerned call your doc and ask but as long as your not having contractions. And your not leaking or extremely crampy, it's normal!
