"i had unprotected sex and i took the pill 30 hours later. i felt a bit drowsy within the first few hours, however over the next two weeks i experienced cramping. the cramps were really bad.10 days after taking the pill my breasts completely swelled. my nipples were always hard and the pain was unbearable. i was convinced i was pregnant. the cramps continued and i was experiencing back pain. then the pain in my breasts finally began to subside and i got my period the next day, exactly when i was supposed to. it was a little bit heavier than usual but i&#039;ve never been happier to be on my period. the pill messes up your body due to increase of hormones. i&#039;ve read it makes you feel exactly as pregnant women do so don&#039;t panic over the symptoms!"
