hey, me and my boyfriend had sex 4 days back. he says he's pretty sure that he didn't ejaculate but he didn't want to risk it so i had a contraceptive pill (Unwanted 72) within 30 minutes of the intercourse.

previously i had problems regarding my periods since they were irregular and would go on till 2-3 weeks almost so to regulate it i was asked to have mala-N for six months. i had it for five months and stopped 2 months back. last time my periods were 4-5 days late and this time it's been 34 days since my periods started last i.e. 6 days late... am i okay?
