So two days ago I tested it was negative of course I wipe and there was a streak of blood with some brown I assumed it was my period put on a pad and nothing the rest of the day and the next night I started cramping really bad went to the bathroom and there was a bunch of old brown blood then I wake up that morning expecting blood and nothing just severe right breast pain

Is it worth taking another test? Or is my period just having a rough start I’m officially 4days late
