5 negative at home tests. Af was due 12-1. The only month I tracked with opk, 2 months ago, I ovulated on cd20. Also, negative blood test. The only other time I was late more then 2 days was when I got pregnant with my daughter. My doctor says come back in 10 days if I still haven't started. What's going on? Has anyone got a bfp after 8 days late worth of bfn?
