"i took the pill 20 or so hours after unprotected sex and when i woke up in the morning, i had almost immediate results. i woke up with lower abdominal pains (which is normal), and went about my daily routine. i started to experience a great amount of fatigue and i really honestly just wanted to sleep the whole day. i am telling you, the side effects are not too bad. although, i missed my period. after i missed my period i began panicking but today i got my period! all is well, please do not stress out if you haven&#039;t gotten your period. mine was 4 days late but this pill really works and it is worth the 50 or so dollars! :)"
