"wow ladies!!!! all i have to say is &quot;wow&quot;. this stuff seriously works. i&#039;m 18 years old and i had sex with my boyfriend on the 22nd of january, and while he was pulling out, the condom stayed inside of me. we were worried about any leakage so i decided to take plan b about 18 hours later.  according to my period tracker it said that i was supposed to ovulate on the 21st so i started to freak out thinking i could&#039;ve been ovulating while i took plan b. my side effects were very little but it did make more anxious about my period starting and a little bit more irritable than i usually am the week before my period. i was only a day late for my period and i could not be happier. this medicine is a lifesaver. just sit back, relax, and don&#039;t stress"
