"i had unprotected sex the day before ovulation.  i wasn&#039;t aware at that time i was extremely fertile. i took plan b within 6 hours after intercourse. i can&#039;t lie, i absolutely knew i was pregnant!  i had all the symptoms. i was nauseated,  headaches, swollen breasts, and i cramped daily. i was so ecstatic to see my period come on the same day it was expected! birth control pills will be started today!  thanks plan b!"
