"i had unprotected sex two days after my period, i took the plan b one step less than 24 hours later and low and behold it did not work. i even got the symptoms from the pill a week later. i was bleeding like a period for 4 days. and took 5 at home pregnancy tests which all very lightly came back positive. i called plan b&#039;s number on the box and reported my experience. they took down the information and pull number on the box. let me tell you people....please just use a condom. i just found out yesterday i was pregnant and i&#039;m now a mess. please be safe and don&#039;t rely on your partner to be safe because i thought it was obvious he needed to pull out. (sorry for being graphic) :(  to be honest i dont think plan b even works."
