emergency contraception
"Firstly yes it worked HOWEVER after my experience i think this pill should be illegal! It messed me up and i now regret taking it. 

It said on the leaflet your next period may be a few DAYS late and if any longer than 7 to do a pregnancy test) i did not get my period so i did tests.. all negative.. 3 MONTHS later.. finally got a period and the pain was just horrific. I will never take a pill like this again. Horrible horrible thing!"
