Hello and Welcome to ‘Ask A Doctor’ service.
I have reviewed your query and here is my advice. Postinor 2
is an emergency contraceptive
which contains levonorgestrel
. High doses of progestogen in levonorgestrel treatments may induce progestogen withdrawal bleeding a few days after the pills are taken. So its common to have such kind of bleeding after taking pill. It is not an overdose.
Hope I have answered your query. Let me know if I can assist you further.
