Hips Don't Lie

Can I just say, I'm only 17 (and a half) weeks, and my hips, especially the right one, are seriously messing with me. This is baby #3 and I've never experienced this before... and it's still so early in the pregnancy!!! If I get up from laying/sitting, for any amount of time, it hurts so bad to get up and walk, it's like they're saying, "nope, not today you fatass." Any suggestions from mom's who've experienced this??
