I've been tracking my ovulation last month when I ovulated my test showed me my ovulation day then the day after the second line was gone, this month I ovulated on the 21st (monday) I decided to take another test on the Tuesday and a second faint line was there didn't think much to it anyways tested again Wednesday and so on till today and as you can see from this photo there's still a faint second line :/ does anyone have any idea what this could be? Test and photo taken several minutes ago.
