Period or pregnant?

Brianna

About 4-5 days before my schedule period I had brown/pinky blood thought it could be implantation bleeding so I took a test one day before my missed period and the test was negative. So I thought I’d get my regular period. I was supposed to start on February 1st but didn’t start. On the second I had light bleeding, so I thought I started. But the third there was nothing. And the fourth on and off bleeding all day but only when I wiped. Has this happened to anyone? And what happened, did you start your period or were you pregnant? TIA
