Had a faint positive and then it vanished!? Please help!

I tested this morning with a First Response Rapid Results and thought I had finally gotten my bfp until a minute later when the second little line disappeared.

The first photo shows the line and then in the second I see nothing. I’m devastated once again even with a very late period and tons of symptoms.

Has this happened to anyone else? Could this possibly lead up to a positive? With my first pregnancy I didn’t get a faint until 8 weeks along.
