Just Relaxin
From WebMD:

The hormone relaxin causes the ligaments in your pelvis to widen and become flexible so that birth will be easier. You may notice your hips widen, and they may also feel a little floppy from the relaxin. Because relaxin increases flexibility, it is easy to injure yourself during exercise so be careful not to overstretch your joints.

This is one of the reasons why pregnant women are told to avoid heavy lifting during pregnancy. Now, a sensible person might extrapolate and avoid certain other activities very late in pregnancy. A sensible person might figure that with 6+ pounds of fetus hovering just over her pelvis, it might not be such a bright idea to dance a quickstep.

You're probably not aware on a day-to-day basis that your pelvis is actually two separate halves that are joined in the front by a bit of ligament. You probably don't think of that bit as a joint, after all, normally it doesn't move. Of course, if you were 37.5 weeks pregnant and dancing the quickstep, that joint might suddenly pop, much like other joints sometimes pop, but with much more stretching of muscles that normally don't stretch so much...

I am not a sensible person, it would seem. I think I pulled my groin. In the immortal words of Homer Simpson, "D'oh!"

I popped my symphysis pubis stepping out of the bathtub while I was in the hospital. I was hobbling around for days (and needed a Percocet that night - for reference, I didn't need a Percocet after my C-section drugs wore off).

At least you were doing something fun.

I also popped my pubic symphysis during my first pregnancy. Scared the bejeesus out of me, since it was halfway through the second trimester. I went to Beth Israel and was diagnosed. Horrible pain. I felt like I was unhinged. By the end of the pregnancy, I could barely walk and had to use a cane to get around. I completely ground down the outer heels of my Danskos due to the rolling, penguin-like gait I had to use. Fortunately, this pain subsided almost immediately after giving birth.

For the second pregnancy, I was ready. I did lots of kegel and abdominal strengthening exercises as soon as I found out I was pregnant, and this significantly reduced the discomfort later on.

At any rate, if you have popped your pubic symphysis, there is sadly nothing you can do about it now. Try some of the strain-reducing belts (this did not work for me), but otherwise just try to keep off your feet as much as possible. Do discuss it with your doctor at your next checkup, though, since this will likely make delivery much more painful, and that may change your decisions about anaesthesia.

Oh, and just to brighten up your day further, this condition is permanent. I've heard that some dancers do this deliberately to improve their flexibility. It will generally not bother you when you're not carrying vast amounts of extra weight right on your pelvis, but it will affect you in subsequent pregnancies.
