I had sex sept 9 (the 2nd week of my menstrule cycle and 2 days before my ovulation date). The condom came halfway off so we thought it would be safe to take a plan B. I took Plan B one step a few hours later that day. 5 days later on sept 14 I experienced brown blood in my underwear, I thought it was just spotting as a side affect but it then grew heavy with blood clots in it just like my period. It lasted 5 days which is my normal period length, but I wasn’t due for my period for another 2 weeks. Now it is sept 23 and I am supposed to get my period for this month on the 26th. I am confused about whether the bleeding that occurred was spotting or my period and whether that isn’t an indication that the plan B worked or not.
