evap or BFP?

Kay • 1 healthy 4 year old. 4 early m/c in the last year. TTC for baby #2!
I took this pregnancy test around 1:30 after 5 mins it looked like a BFN. I left it on the counter and forgot about it. I come back to it 5 hours later to find a faint line. Could it be a BFP or evap line? Can you see the line? I am TTC, 4 M/c, 1 FT son, and on 3rd of Femara.
