Has anyone else needed to use a brace early on in their pregnancy?

With my first, my pelvis had separated, and I couldn't walk without a walker. It started about halfway through my pregnancy. But I'm 11 weeks with my second, and I've been experiencing the same kind of pain in my hips and pelvis again. When I went to my chiropractor he said it seemed like my ligaments were "over loosening" and he was going to recommend putting me in a brace. He didn't get too in detail about it just yet, but it worried me a little because I'm still so early. I can't imagine how bad it's going to get once I get further along.

Has anyone else experienced anything like this?
