"i had sex for the first time ever, unprotected, on my day of ovulation. he pulled out but i was still anxious because i knew that my sisters and i were all a result of the pull out method... so we got plan b and i took it probably an hour and a half after sex. i was really worried because i had no immediate side effects and i had &quot;the feeling that i was pregnant.&quot; (the only side affect that i ever got was bloody noses for about six days after i took the pill.) after reading the reviews on here  i felt a lot better, but the thought of pregnancy still nagged at me. a week after sex i took two tests, both negative. my period started about five days early. try not to stress out, this pill actually works"
