These are for my friend she does not have this app but her and her husband just started ttc this month and she is 9 days away from when she is supposed to get her af. She took this test last night and said when she first took it she thought she saw a very faint line but didn't think anything of it and disregarded it but then a few hours later it looked like this. I know it is invalid after the time window but from what I've seen most evap lines are skinnier or offset or not really colored so I'm not sure?
