Early this year, I took the Plan B pill, also known as the Morning After pill. The next month I noticed spotting, and then two months later as well. I was told by more than one nurse at Family Planning that I shouldn't worry about this. I then started taking oral contraceptives, and have for several months now. I had spotting for several days after my first intercourse in June, and again was told this wasn't abnormal. Now I am having spotting again, and I am concerned. What is the likliest cause of this, and what should I do?
