I did a CVS blue pregnancy test yesterday as I was on my day 28, it showed nothing I came back after awhile ripped it apart and the strip showed extremely faint light blue line( image not attaching as I am a new user) I went to Walmart got FR and tested at night negative, in the morning repeated CVS blue test and no second line ripped it apart and checked it still no line. I am wondering why the first strip from the same brand showed a faint line. Is it evap line or positive result. Just going crazy. I am due for my period today so don't want to waste money on more tests. If someone can help relieve my anxiety?
