Severe pain?

I am currently 10w2d pregnant.
I coughed earlier while laying down and sat up because of severe, sharp stabbing pain in my lower abdomen. Shortly after I got sick. The sharp pain went away.. But now I have had light/mild cramping with no bleeding. 
Any ladies know what this could be?
Should I go to ER? 
Or just call my dr on Monday? 
Thank you
