Normal? Or should I call my doctor?

So last night I woke up and my lower abdomen felt tired or like I had done a bunch of sit ups. I also felt dizzy and nauseous, almost like I had motion sickness. It kinda worried me but the pain or nausea wasn't to crazy bad. Should I call my doctor still and see what it could have been? Has anyone else had this? I am 19 weeks.
