"okay, just like most people on here i decided to write a review if this pill worked. my previous period started on december 30, 2016. i had unprotected sex towards the end of my period on january 5th, 2017. the first time, my boyfriend pulled out but the second time, we kept going without a condom and i think there may have been some sperm in me. i freak out and went to planned parenthood on january 6th, 2017 to get emergency contraceptive. i got the generic formula called &quot;econtra ez&quot; but it worked just as fine! my period came today on january 29th, 2017. i was psyching myself out reading all these reviews but i&#039;ve taken plan b, ella, next choice and etc... always worked! going to be on birth control pills after period!"
