Hello dr. i am from india. on august me & my husband did unprotected sex after that i took ipill 72 ecp. my periods cm on 25 aug..ther was only 2 day?

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.
