ectopic or normal?

Marissa
I think I'm almost 6 weeks my dr appointment is in three weeks but I've been having one sided pain next to my belly button. Sometimes it gets as high as my ribs or it moves to my wait or back. It hurts worse when I run like a side stitch but I'm very active and run a lot so I don't usually get pain. I'm worried these are symptoms of ectopic pregnancy. It's a Sunday and can't talk to my dr. Has anyone else had similar symptoms? 
Rarely the pain is lower like a period cramp but usually it's a sharp pain
