is prescribed for arrest of bleeding and it is not a hormone. Lutenyl is the hormone progesterone
which is usually given for 10 days for treatment of dysfunctional uterine bleeding
from 16th to 25th day of the cycle. Usually, withdrawal bleeding occurs within 4-5 days after stopping the drug. Your bleeding is a result of this. So do not worry. It is most likely to be normal and subside as in a normal period. Please consult your doctor for further advice. Good luck.
