... finished inside me. 45 minutes after the incident I bought Plan B and took it. I haven't had and spotting or bleeding or any other symptoms that were listed on the box until after 2 weeks of taking and I am currently 13 days late for my period. I am also experiencing cramps for the last 4 days as if I were about to start, and I have had very tender breasts. I have taken 3 pregnancy tests and they were all negative. Is it normal to be this late after taking the pill? Should I be worried?
