I'm sorry but I am getting so tired of reading all these posts about faint lines, tweaking, "do you see it?"....
If you have to strain to see the line or tweak or post a picture asking other people..... It's probably not there.
Just wait another few days and test again.
I know you're excited and I know you want it to say YES but asking about test lines that are clearly invisible is getting tiring.
Please just have patience and test again later.
