will dr do ultrasound?

At the beginning of the week I ran into something and it hit my belly. Didn't really hurt when it happened and I didn't hit it very hard but since then I've had a little bit of a pain in my belly near where it got hit. No cramping or bleeding and the pain isn't severe. I have a check up at the ob tomorrow. I'm for sure going to tell him about it...do you think he will do an ultrasound to check and make sure everything is ok?
