Car accidents

So a little while ago ( roughly 30 minutes before post)I was stopped at a red light and the car behind me stopped and then hit me... My car has no damage & i only felt a small jolt, should i go into the ER or wait til morning (it is almost 8 pm) to see my obgyn? I'm not really in pain and there are no signs of bruising or bleeding.... & baby is moving regularly still... Just super nervous I'm 29 weeks pregnant and just dont want to do the wrong thing....

I am waiting for a call back from the nurse line just curious what anyone else would do.
