I had unprotected sex on 8/2 af was due 8/14. Started lightly bleeding on 8/10 and lasted for 3 days and then nothing after that, took a test shortly after but got a bfn. Next af was due today but I've had nothing but white thick discharge, my last normal period started on 7/17. what do you ladies think?
