"i had unprotected sex a couple of days after my period ended. after i realized what i had done, i began panicking and purchased plan b about 22 hours after. i was so stressed and miserable for a month, and it just so happened that i didn&#039;t get my period the week i was due. i had crazy symptoms, incredibly sore breasts, horrible cramps for a week. and then i randomly started spotting for about 4 days. i really was convinced i was pregnant. a week after my expected period, i finally got it! ladies, i know it&#039;s impossible not to stress. but i believe the amount of stress i put myself under caused my period to be even later than it should have been. but trust me, this pill works."
