If you took it within 72 hours of the unprotected sex, and you did bleed -- yes it worked. I had the same effect after I used it a long time ago, I bled heavily.
Ok, i've been reading up about taking plan b and sometimes it not working properly and turning into a pregnancy! ever since ive missed my period and have just had some spotting. I already have a 2 year old and am not really ready for another one, yet my boyfriend is ready. Well, Here it goes.. my last period was July25-31 which my periods are VERY heavy usually. I had unprotected sex the 18th of August, again on the 20th of august then took the plan b the next day,,again sex the 25th then i noticed a bit of brown discharge it was hardly there. my period was due august 22nd which i have missed. then on the 27th i started spotting bright pink with some clots small stringy almost black/dark red. its very light. My breasts hurt as if i am pregnant i have small cramping diarhia and have been extra tired. Usually my periods start off with spotting and before the end of the day become very heavy i usually wear a tampon and a pad. this is very abnormal for me. Any suggestions?
