emergency contraception
"I Took my last birth control active pill 2 days late. Had unprotected sex March 1st on my placebo week, 2 days before my period was due and 36 hours later took plan b. 5 days later On March 6th I was spotting and bleeding very light more like a brown discharge for 4 days. My period finally came yesterday March 30th. I freaked out the whole month and took 5 pregnancy tests and they were all negative. The pill works!!! You just have to be patient."
