BFP? BFN?

Hi everyone. Have any of u experienced tenderness of breast, abdominal cramps, nauseous, missed period for more than 5 days & a “line” of bleeding? I’ve missed my period for a week now & I’ve never missed my period for more than 2 days except for being pregnant with my firstborn. First 2 days of missed period turned to be a BFN. Sexually active too. Am i pregnant? Or is this a pms?
