I did not have intercourse, but my boyfriend ejaculated somewhat close to the area. So to be safe, rather than sorry, I took plan B in the next few hours. After a few days, I had some brown spotting and then dark bleeding for about three days, at which point it lightened up and became more like spotting. After a month and a week from the day of taking plan B, I got my normal period although it was shorter than usual. It is now the month after that, and i have not gotten my period yet. It is already three days past last month's date. Can I still be pregnant? I did not have any sexual contact since that day and time.
