I posted a question last week about whether I could be pregnant again. Well I was supposed to get AF thursday and still AF is not here. I tested on the day it was supposed to come (Thursday) and it said BFN (it was not FMU) I tested around 3 oclock. I am scared to test again and it will still say BFN. Am I just late? Should I call the doctor monday and ask for blood work? I'm not sure how late I have to be before they will test me. I'm just anxious and wish I knew whether I am just late or preggo.
