Do you seen lines?? So scared

I missed my period by 8 days. I’m cramping like where my ovaries are. Me and my bf broke up so I’m hoping it’s negative. I’ve never missed a period. I’m regular. I’m nauseous but I think that’s from me eating dairy because I’m lactose intolerant. And I feel as if my period is coming on so I go to the bathroom but nothing there. Digital test read “not pregnant” always use protection.
