Brief Answer:
Varying period duration

Detailed Answer:

Hi,

Periods can be heavy or light with varying flow and duration after taking plan B.

This is because of the hormonal imbalance and interference in the normal menstrual cycle caused by the hormonal effect of the pill.
The duration of the period after taking the pill can be anywhere between 1 day to 10 days.

There is nothing to worry about.

Hope I have answered your query. Let me know if I can assist you further.
