"i had unprotected intercourse twice within the range of the 72 hours. i asked a friend of mine who has used plan b and the morning after i purchased plan b for $41.80 (price is after taxes). came home, took them, felt fine. no side effects. i was supposed to get my period 3 days later but i didn&#039;t. i got minor cramps here and there but nothing too severe. now exactly a week after i took them i got my period (5 days late). this pill works but i never ever get severe period cramps. my period cramps this time are very severe and painful to the point where i can barely move. this has never happened to me before and i hope it lightens up in the next couple of days."
