Faint line

I feel like I've been going crazy the past couple of days. I started testing super early and yesterday I swear I kept questioning whether I seen a line or not it was that faint but I definitely think there is the faintest of lines today.🤞 We only had sex 3 times total this month and none where when my app predicted my ovulation period. I only got one surge on a ovulation kit but afterwards tested an hour later because it says not to do it first thing in the morning and it was gone, back to a faint line.
