ipill/unwanted 72 is an emergency contraceptive pill. It is to be used for emergency purposes only i.e. for situations when your conventional contraceptive technique fails. (Eg. Tear of condom, failure of attempt to ejaculate outside vagina, etc)
It is not to be used as a routine contraceptive as it is a high dose hormonal pill which disturbs the menstrual cycle causing irregular spotting for 1-2 months.
Next Steps
No need for iPill if used condom on day 2 of sex.
