My last period was Feburary 28th and lasted about 5 days. I had protected sex on the 24th of March when the condom broke. I went to the store the next day and bought Plan B One-Step and took it, this was about 16 hours after the incident. Today is the 28th, so I am expecting my period but haven't got it yet. I know taking the pill can affect your period but I'm just still a little worried about it and am looking for some advice, reassurance, anything will help! :)
