I have never "missed" a period. I have been a few days (1-3) late before, but never missed. I have been on bcp pills for almost 6 years. my last period was sept 4th, so I am now going on 2 weeks late. I have taken about 5 home pregnancy test, all negative. I have tested in the am, at night, with lots of fluids without fluids. everything. I have an appt with my obgyn, but I am still anxious to know what is going on. any ideas?
