AF is 4 days late and after getting a barely visible BFP line 48 hours ago I just took another test.
It's still very feint...
Would you be concerned?
I know I need to step away from the tests but I just can't. 
So hope this isn't a chemical pregnancy.
Feeling quite confused - I want to be happy but it's concerning me just how feint it is.
Or am I worrying way to soon?
