Is there a second line?

My husband and I have been trying for 2 years for a healthy pregnancy (tried 7 months got pregnant had a miscarriage 3 months later and have been trying since) and we decided rather than trying just naturally we would track my ovulation and well low and behold I ovulated later than the apps calculated so we baby danced when I started getting dark opks and I think I have a faint line (about 6 dpo so maybe to early) but I see it,hubby sees it and my closest friend who is staying with me temporarily also sees it do any of you?
