Cervical mucus

Normal. Nothing has happened yet.

Implantation has not even occurred yet at 3 dpo. Implantation (on average) normally occurs at 9 dpo, as early as 7 dpo, or as late as 12 dpo if an egg gets fertilized. And unfortunately cervical mucus is not an indicator of pregnancy; as it differs for every woman. Cervical Mucus simply changes throughout the month. As long as there is there is no foul odor, abnormal color, abnormal consistency, burning or itch, then you are fine. Normal.
