interesting day

I'm writing this partly to vent, partly just to get some community support. This morning on my way to work, I was rear-ended by a vehicle moving as slowly as one could be moving. We were both sitting still at the light to turn right and he creeped forward too much and hit me. There was no damage to the car, and I probably got more jostled around driving on a few dirt roads last weekend, but nevertheless it really freaked me out. I called the doctor and they told me as long as there was no bleeding or pain (or leakage - like amniotic fluid) I shouldn't worry and everything should be fine. I'm a first time mom, 17weeks today, and trying to relax about this, but I'm still nervous. I am not having any bleeding, I'm not really having any pain besides the normal twinges of my belly growing, but I'm on edge. I'm hyper-aware of every feeling I have in my belly. Anyone experience anything similar?
