According to ff, I'm 14 dpo. My temps are still above the cover line. I've been getting bfn since 8 dpo.... Clear bfn not even a squinter! What's really making me question is last time I got my bfp I had this terrible cold - cough, lost voice, congestion.... Unfortunately that ended in a mc but yesterday I started with the exact same cold symptoms clear out of the blue just like last time... 
Am I out now that it's so late in the cycle?
