Car Accident!

Hi guys, I am about four weeks pregnant. I have not been to my first appointment yet or anything. This morning i was in a minor car accident. I rear ended the guy in front of me. My airbags did not go off and I do not feel any pain or discomfort. I am not cramping or bleeding. I did go to my OB and had blood drawn. They will check my levels and get back to me tomorrow.

In the meantime, I am of course panicking and worried sick. I am a complete emotional wreck. Does anyone have any input or experience with anything like this?

Thanks in advance.
