Upper abdominal cramping

I’m 8 weeks pregnant and today I have been having what feels like a consistent band of cramping pain across the upper part of my abdomen which is worse towards the left side. It is worse when I am moving around and sort of came out of nowhere. It isn’t accompanied by any strange symptoms, just the normal pregnancy nausea and the light, intermittent “pulling” feeling in my lower abdomen.

Is this something I should be worried about? My doctor isn’t available for a few days so really hoping it’s nothing.
