Levonorgestrel
"To all the ladies reading the reviews and stressing out stop. This pill is very affective but stress will delay your period even more. Mine finally came today 9 days late. And I took the pill on day three after the 'accident'. I just kept stressing and stressing having parsley in tea and taking in lots of vitamin c and cinnamon paranoid. Reading reviews all day. The incident happened like 5 days before my period was supposed to start so this waiting game seemed like forever. My friends kept telling me to relax but I felt like I was going to die being 18 and all with overprotective parents. It was my first time and it didnt happened all the way but my friends told me about precum so I was terrified. Having bad cramps right now and bleedin:D"
