HI everyone, I did a test this morning it came up with a second line but it dissapeared before the 10 mins I've had another look at it just before and the second line is back but very very faint, I've tried to scan it but it doesent come up. Do you think I should disreguard it and just wait another few days nad test again?

Af is due on Monday the test was a fortel not the ultra one though.
What do you think.
I'm on 14DPO.
