Confused

S
So my af has been 12 days late and this morning I woke up test and I automatically saw a BFN and went to wipe saw blood so thought af was here. No biggie right, a couple hours later my husband got up to get ready for work and all sudden asked me what I saw when I took the test. I told him one line and he was like are you sure and know I'm thinking what is this man talking about. I walking in the bathroom and see the test with two lines but one is very faint. Long story short, is this a faint line or just an old test??
