Intense upper stomach pain

I woke up this morning with intense pain in my upper stomach near my ribs. I'm 5 weeks 5 days pregnant. It's a constant pain but sometimes they'll be a wave where its worse.

The pain has been there for an hour now and doesn't seem to be getting any better.

Has anyone had anything like this before? I'm not sure if I should be calling my doctor. There's no way I'd be able to wait in the line to see one.
