Took ipill withing a gap of 20 days twice and been a week since the last pill but no bleeding . worried about pregnancy.

Can do preg. test: Taking Plan B, i-pill, or other emergency contraception pills can alter the timing or the quality of the current menstrual cycle bleeding and perhaps the upcoming cycle. One should check a urine pregnancy 3 weeks after taking sex, because i-pill works most of the time but not all of the time. Also, be sure to use a "Plan A" as regular, reliable contraception to avoid needing i-pill again.
