"plan b one step definitely works. my last period ended the 19th of july and i had unprotected sex the 23rd and he came inside of me. within an hour of the sex i took plan b. the first couple of days i just felt extremely hormonal and on edge, resulting in some mood swings. a week following (aug 1-5) i experienced spotting that was brownish red and this lasted a week.  then the extremely tender breasts came, nausea and bloating a week before my expected period. my vagina was also very dry throughout the two weeks likely due to the high hormone dosage. consequently i also got a yeast infection due to the hormonal imbalance. regardless of all symptoms, i got my period on time and it is extremely heavy.  relax and try not to stress. it works!"
