So i was supposed to start the 5th. I tested the 4th 6th 8th and 11th and all BFN. Scheduled a blood test with doctor on the 19th if I don't start by then but what is going on? Im not regular with my periods but it has never been this late since I found out I was pregnant with my daughter 4 years ago. If I'm not pregnant then why have I not started and if I am why is it not showing a BFP. Im nervous to test again because every BFN is a heart break. Has this happened to anyone else and what was the outcome?
