"so after reading all the reviews on here which totally saved me from having a panic attack i had to write about my experience. i&#039;m 20 years old and me and my bf had unprotected sex on august 29th, he pulled out but i was still super paranoid so i took plan b 11 hours later. i had absolutely no side effects so after about a week i was convinced that the pill didn&#039;t work for me and even started thinking about how i was going to tell my parents, my friends, the whole thing! so crazy i know.. so anyways i got my period today and am so happy. trust me even if you don&#039;t experience any side effects does not mean the pill isn&#039;t working! i promise, just try not to freak out and keep yourself busy. also my period came a little less then a week early"
