getting discouraged

Brandi • My name is Brandi and my fiancé`s name is Joe. I`m 23 he`s 25. TTC baby #1. I`m a hair stylist and he`s in flooring.
So 2 days ago I took a test and I was so convinced I saw a faint line. I posted the picture and to my surprise I wasn't the only one to see it. This morning I took another test of the same brand and.... Nothing. Now I don't know if I should bother keep testing or what.
