"i had sex (first time) may 31st. although, he didn&#039;t cum inside of me, we thought we should be safe! so that same day (earlier) at 11 almost 12. i bought and took the plan b pill. i took it with water only and was fine. (i don&#039;t have a sensitive stomach). i had no side effects. 5 days after taking it. i had a period like bleeding (one of the side effects of the pill) that lasted 5 days (like my normal period would). i also had a fever. (rare side effect). i had all my symptoms as well. uterus cramps, farting (weird, i know). and lower back pain. after that. i had no other things happen. until, june 25 when i started my period! it&#039;s a little off. (none of my norm period symptoms). it works! relax. don&#039;t stress. you&#039;ll be fine."
