Thanks for your query.This is a 2-pill dose contains 1.5 mg of levonorgestrel
. Don't worry it is effective if taken within 120 hrs. But it is highly effective if taken within 48 hrs. So need not worry, if you miss your periods then please consult your gynaec.
I hope this information has been both informative and helpful for you. In case of any doubt, I will be available for follow ups.
Wish you good health.
