I had a condom break five days ago then less than six hours later took the Plan B pill. At the time of intercourse I had just finished my period about 2 or 3 days prior. Within 15-20 minutes of taking the pill I threw up a little bit. Not a huge upheaval of my stomach contents, but only just a little. Today, five days later, I woke up to a bit of cramping and some dark brown blood when I wiped. Does this mean the pill worked?
I am asking because I heard that women can bleed from a fertilized egg implanting into the uterus and I'm afraid, since I vomited after the pill, that this may be the source of the blood...
