"i took plan b one step on may 1st after unprotected sex. i realized i was ovulating at that time (according to my period calendar) after we had finished. he didn&#039;t go inside me but i was still afraid, so my boyfriend and i went and bought the pill and i took it within an hour and a half. not even exaggerating but i had cramping everyday since i took the pill. i also experienced headaches, and felt really hot here and there, almost as if i had a fever. tender breasts were also a symptom of mine. just yesterday which was the 12th day after taking plan b, my boyfriend and i had protected sex and when i went to clean up i noticed blood! turns out i got my period two days before i was supposed to be due. relieved that it worked for me! good luck"
