Personally, I would go to a doctor to make sure that you didn't actually pull something. But... it could be an extremely rare pregnancy disorder called Pubic Symphisitis (I can't recall exactly how to spell it) or Pubic Symphisis Disorder. It happens when the pregnancy hormones that relax all of your ligaments so that your hips can open for the delivery of your baby go overboard and the ligament that attaches your pubic bone overstreches allowing your hips to more or less fall in and out of joint. The most notable symptom (at least it was for me)is having trouble rolling over in bed or excruciating pain rolling over in bed. I think that you can do a test where you get down on all fours and try to lift your leg out to the side and if you can't do it, it is another symptom. It can also hurt while your just standing or walking, but it is usually intermitent. Sometimes it's really bad and sometimes its not so bad. I had a lot of trouble going up steps. I, like you, thought I had torn something serious and went to the doctor. They really had no idea what was wrong and just wanted to put me on bed rest (military doctors...). I found some stuff on the web and then brought it to the doctors and sure enough, that was what I had. The only thing that they can do for you is 1. put you on pills that tighten up your ligaments, which is not really a good option seeming how you will need them loose for delivery or 2. send you to a chiropractor to continually adjust your pelvis and hips... On a positive note, the pain usually disappears almost immediately after childbirth. And I, too, have two children and had no problems with my first. It all happened with my second. Now that you know the name of the disorder, if you look it up on the web, there is all sorts of information- diagnostic, etc..., but you really should go to the doctor just to be sure:)
