ok ladies listen up!

Sooooo I was totally counting myself out this morning, pink when I wiped so I thought my period was starting 1-2 days early. ThAt was at 730 am and now at 6 pm I still have no flow just pink when I wipe this is very very strange for my period I never ever in my life have had this happen.... I took a test to days ago bfn but now I'm thinking of this is maybe not my period but implantation bleeding or break through bleeding the test would have been negative 2 days ago... right??? Please give me ur opinions ladies
