Late period

My last period was October 13th and now I still haven't had one. My expected period was nov 9th and I still haven't started. Last month I had two negative tests on oct 16th and a neg blood test. I don't have any symptoms but I am really hoping were  pregnant! Does anyone have any advice? I feel the neg blood test should've been accurate but I don't want to test again when I'm not having any symptoms and be disappointed. Thanks in advance
