Light pink spotting on and off after plan b? is this normal at all? it's like salmon colored.

Plan B: Light pink spotting off and on after plan B is normal. Your next menstrual period may come at expected time or a bit early. Your next period might also be more or less heavy when it comes.

Agree w Dr. Poinsett: The color of vaginal blood is usually not of clinical significance. Potential side effects w emergency contraception includes menstrual flow changes (spotting, bleeding, early or late period). This is likely a Plan B side effect.
