"i finished my period on december 24 then i had unprotected sex with my boyfriend on december 25 around 5am. he swore he didn&#039;t ejaculate inside, but i being worried about pre cum, took plan b around 1pm, 7-8 hours later. on december 30, i was bleeding heavily, as if on my period for about 5 days, but the blood was a brownish type of color. i was really paranoid, checking and reading every review there was on this pill. i did have nausea &amp; dizziness symptoms. i got really afraid because my period was due on december 19, but it never arrived. it is now february 4, &amp; i&#039;ve never been happier in seeing blood! i was 19 days late! relax, let the pill do its job"
