Pelvic Pain Begins

I am about 14 weeks, and the pain in my pelvis has begun - earlier than the last pregnancy, so I am worried how bad it will get by the end of this one. If I walk around too much of course it gets worse, but it can flare up when I have been sitting down for a long time then get up, too. My hips have been giving me curry lately, too. And the round ligament pain has also started - when I roll over in bed it's like someone is cutting my insides out. Ahhh... But I wouldn't have it any other way.
