DH and I were driving when an imbecile decided to cut us off and stop. We weren't going extremely fast, but it was still more than 40 mph. As a result DH slammed on the brakes to prevent an accident which caused a sharp pain in my abs and they've been hurting and sore since then about an hour. What's the likelihood that this is placental abruption? Should I try to call my doctor's office? They aren't exactly reliable with calling back and since it's the weekend I have a feeling they more than likely wont return any messages until Monday if I'm lucky. Am I just overly worried?
