"hey girls! i spent a lot of time googling about this and never found anything that put my mind at ease so i wanna share my experiences! i&#039;m 21 years old and i had sex with my ex and being the paranoid person that i am freaked out and took plan b 38 hours after. i got everything from nausea, breast tenderness headaches it was awful! at first! i got brownish discharge a week after taking it then 3 weeks later which is today jan 30th i got my period after being 2 days late. point is don&#039;t worry! plan b works very well but it will put your body through a huge mind distortion to the point where you&#039;ll think you&#039;re pregnant but you&#039;re not! it&#039;s insane. i lost much sleep over it and stressed myself out over nothing. i hope this helps."
