Hello, I've had unprotected sex last Feb 15 and took emergency contraceptives on the 19th. My last period was Feb 6. I experienced light bleeding with dark and clotted discharge last Feb 27 which lasted for 4-5 days. What does my bleeding means, is that my period already? If not, is it possible that my period is late? I already took 2 pregnancy tests and both resulted negative. I hope you can help me lessen my anxiety. Thank you.
