"my boyfriend and i had unprotected sex around 11pm and he pulled out but i&#039;m not sure if he did it end time. just to be safe i purchased the pill the next morning and took it at 8am. i started my period 3 days after . the only bad thing about this pill is that i had extremely bad cramps and a little nausea . the pill does work though! i would recommend it!:) don&#039;t worry ladies and don&#039;t stress out!"
