Advice ???

I started my period I think? Well for the past three days it started out as brown but not as heavy? Like light . And then between these past three days their was a moment where it had a clot ? And was brownish red? I’ve cramped slightly ? And my upper stomach has hurt ? But it still hasn’t been heavy at all? Like it’s like . Is this a period ? And is this normal? Cause it’s the first time itsdone this .
