"hello, i usally dont write any kind of reviews. but i thought i should share my experience. so i had a sex with a guy about a month ago. we used condom but it broke and he came inside me. i was not on birth control and never took a pill before. we went out and got the pill and took it within 45 minutes after that happened. a day after, i had a little cramps, and started to getting tired and couldn&#039;t get up early in the morning. this is the only side effect i had. i&#039;ve been like that about a week and i had a period. yes, i had a period exactly a week after. but it was different than normal period. i thought that was implantation bleeding. but after three weeks, i checked, and i was not pregnant. don&#039;t get too stressed out ! thank you plan b !"
