Glow told me to take a pregnancy test today. I am 11 DPO & AF is due in 4 days.. I bought the CVS brand early response.. Which says that it can detect pregnancy up to 5 days before your expected period.. Both tests came back negative. The one was a CLEAR negative & the second the line was kind of blurry. Has anyone ever used these tests? Am I testing too early? Any advice PLEASE COMMENT.
