Ugh so frustrating!

I am 6 days late for AF today. Ive taken 3 tests, every 2 days. NEGATIVE! My Aunt had something that made ALL urine tests negative when she was pregnant with all 3 of her children, it was only blood tests that showed it. So im wondering if i could have that same thing. So i called my doctor and told them what is going on and my family history, they said i have to be 45-60 days late. Im so frustrated. 😑 like i need to know. 😔😔😔
