tHAT IS NOT HOW THE MORNING AFTER PILL WORKS, it does not work by forcing a period at all..I should know, I work in womens healthcare and am educated accordingly.
Website for plan B =)...A good source to back me up..

THE MORNING AFTER pill works by STOPPING OVULATION, and 'possibly' preventing a fertilized egg from attatching to the uterine lining. OUR BODIES naturally excrete progestin after we ovulate, so this tricks the body into thinking that it ovulated... SO you will get a period quite quickly after using plan b.
#2 The dose of progestin DOES thin out the uterine lining, so this is why heavy bleeding is common after using PLAN B. IT IS obviously a higher dose than what our bodies would excrete naturally.. PLAN B can cause irregular spotting and bleeding after use.
