Hi Welcome to HEALTHCARE MAGIC..
I have gone through your query and can understand your concern...
Intake of an
emergency contraceptive pill like Unwanted 72 can cause early bleeding before your next expected period. The bleeding you had must be
breakthrough bleeding which normally occurs within 3 weeks of intake of postinor 2 pill. This is normal feature of intake of Unwanted 72 pill & you should not be much concerned about it.
This bleeding is due to high dose of
levonorgestrel in an emergency contraceptive pill like unwanted 72, which disrupts your normal menstrual cycle & cause this type of bleeding.You could also have your next period delayed. Breakthrough bleeding most probably means that intake of Unwanted 72 was successful in preventing pregnancy.
Don't take Unwanted 72 pill too frequently. Use condom or regular contraceptive pill regularly as method of
contraception in future. These pill can cause
irregular periods & other serious side effects.
Refer to a gynaecologist for more queries
Don't worry you would be fine
Hope this information helps
