"i worried myself sick and turned out fine so i thought i&#039;d ease someone else&#039;s mind. i got drunk and had unprotected sex with a friend aug 12 at about 3 am. neither of us could remember if he pulled out and pretty sure i was fertile at this time. my last period started july 31st and my cycle is about 22 days. i took take action at noon the next day so about 9 hrs later. i had no side effects accept major bloating 2 and 3 days later and nothing at all for another week. i was panicking and convinced i was pregnant. my expected period was the 22nd. long story short, i started spotting the 21st (today) and just got it full on. came on time! don&#039;t panic yourself, i trust in this pill!! i&#039;m also going to get on birth control."
