How Long Does Spotting Last on the Pill?

Spotting is very common during the first cycle of pills but normally resolves by the end of the third cycle, according to McKinley Health Center. Women who still experience spotting or any other unpleasant side effects after three cycles of pills should seek medical advice.

Spotting can occur at any time during the cycle of active pills, as explained by McKinley Health Center. Women can reduce their risk of spotting by always taking their pills on time and not missing any active pills. Although spotting is sometimes very light, it can also be as heavy as a period. Spotting usually decreases as more cycles of pills are taken.
