Blue dye BS!

2 days ago...had a very very faint line but it was there with blue dye after 4 months of trying. Didn’t want to get my hopes up after some comments and research on blue dye...but you can’t help but be hopeful! 2 days later and each day taken a First response...both negative. If this is such a common problem with blue dye...they should take them off the market. How disappointing...so ladies don’t waste your time or money on blue.
