AF or implantation?

Tiffany

Ok so my period was due the 14 but it came the 12th and lasted all day ythe 12th and the 13th but that’s it and poof our of nowhere it was a light pink color and stopped not like my normal period that slowly gets lighter then stops it just stopped so I guess what I’m wondering is it possible

to be pregnant? Has anyone experienced this? I never had this happen to me before so I’m worried if something is wrong.
