Confused

My best friend had me post this for the last 2 weeks she has taken a test every day and she says she sees something I see negative cuz she was supposed to start when I started 2 weeks ago and she hasn't yet. She has spotted a little but it was dark and old blood and she took this one today and I told her that it was positive she would like other people's opinion she said it took a few minutes for it to show up cuz she thought it was negative at first
