"i had unprotected sex on august 10, also the last day of my period. he told me he pulled out but i wanted to just be on the safe side since i wasn&#039;t very safe with just word of mouth. took the pill about 3 hours after the incident, and had no side effects. the only side effects were headaches, occasional cramps, and very sore boobs about 2 weeks after taking, also had no spotting which worried me bc seemed like everybody had that. since my period wasn&#039;t due for another month, the waiting killed me. last night i was cramping and woke up this morning to my period, 2 days early! don&#039;t stress, as i did every night and day and didn&#039;t make the situation better. the pill works."
