Okay so me and my girl took multiple pregnancy test before 7/23/24 they all were negative we took one 7/23/24 and it was positive with a faint line then again on 7/26/24 with a darker line but then again today with a first response and it was negative how come ? She does have PCOS so that could be why but I’m dropping a photo of what the test looked like is this a positive or evap line ??
