Four weeks and four days and light clamping should I be worried? Someone?

Britney
I just found out I'm pregnant. I missed my period last Thursday and just decided to take a test Saturday as well as went to a health clinic today and was confirmed I'm pregnant. I've been light clamping tho as if my period is going to start. Is that normal? There's no bleeding, just light clamping. I'm a little worried? Has anyone else had a feeling like this?
