Second line - Visibility
Hi, what is the visibility of a “weak” second line? I took my test 3 – 4 months after the potential exposure, and the result was negative (with only one solid control line after 15 mins).
I wonder whether or not the weak second line, if it was there, could have magically disappeared without my notice in the process and the chance of having a false negative result in my case.
P.S. I looked at the test result the next day and there’s only one control line.
