"i had sex on march 13th and the condom broke. my partner noticed before orgasming luckily, but i didnt want to take the risk of a precum baby.  i also was in my most fertile time, about to hit ovulation.  i took plan b on march 14th, 15 hours later. i experienced spotting 3 days after, that quickly went away. i also experienced bloating, mood swings, feeling hot, etc., that lasted for a little over a week. my expected period was march 30th. i got it yesterday, on april 19th . i was *20* days late. a little over 5 weeks after i took the pill. i took 4 pregnancy tests in this time. 

so, to all freaking out like i did, do know that the pill can make you late (even 20 days late), and make you experience symptoms similiar to pregnancy symptoms."
