"i took plan b about 36 hours after unprotected sex. i literally was so scared i would get pregnant and googled everything on plan b way to much. i&#039;m on birth control but hadn&#039;t been taking it at the same time. i had symptoms throughout that, i was paranoid was pregnancy symptoms like random cramping, lower back pain, and sore breasts. but exactly 3 weeks later, today, i got my period. it is a few days later than when i usually have it, don&#039;t worry, it works! trust it."
