"had unprotected sex sunday morning and got/took the pill the next day. felt perfectly fine that day but everyday up until today i have been cramping and my breasts have been super tender, but i knew it was normal since it was stated as one of the side effects. but i didn&#039;t know it was going to make me get my period so early. i&#039;m supposed to get it two weeks from now but got it today. i&#039;m glad i did because now i have some closure knowing that it worked!"
