Implantation bleeding after BFP???

Brooklynn

Have any of you ladies had implantation bleeding after your BFP??? I got my BFP at 12dpo, and the evening of 13dpo I had some light pink bleeding that went back to light light brown and it continued to be that color and now I have a little more of the light pink bleeding again at 15dpo....I know I shouldn’t stress but do you think I should be concerned??
