"it works! i took it one hour after the condom broke and had my period 5 days later! if you take it sooner than 24 hours, you&#039;re absolutely guaranteed that it&#039;ll work! so stop worrying. you may have more discomforts than normal, but actually, i had no cramps at all and no aching! i always had them for the first two days. lucky me! ladies, it works."
