Too scared...

Stacy
I was due on on Sunday, AF is yet to arrive.
​I'm too scared to take a test because I don't want it to be another negative. It's been a year now TTC and I so desperately want this more than anything in the world!
​The latest I've been was a week, got all excited and took a test-negative. Was so confused, literally AF appeared the next day!!
​I just don't want another negative but I'm scared the longer I put it off the more my hopes will build. 
​Any advice would be great thanks!! :D
