"i promise to write about this if it work girls i know you are worried, i swear i was like that when my bf ejaculated in me. at first i thought this pill work all year around so i allowed him but i later read that if you ovulated, it might not work so i was freaking out for months and i went through like 20+ pregnancy tests. i took plan b in february and now it&#039;s july so i can say this pill works. it does made me have pms/pregnancy symptoms, i was spotting and my period was light. that alone made me wonder is this was implanation bleeding, luckily it&#039;s not. for me, it affected my period for so many months, it was much lighter and shorter before. again i recommend this for emergency only. i now practice nfp or natural family planning."
