Hey y'all! So I'm a total newbie here, this is my first cycle TTC after 8 years of BC and I've only been using this app for about 3 weeks, so I've got a question about the blue dye vs. pink dye tests! My only experience with pregnancy tests was 8 years ago back in college when I had a "scare" -crazy how now all we want to see are positive tests! And I do remember using the first response pink dye, but I have seen threads on here that talk about the blue dye tests not being accurate and telling people to re-test with a pink dye... anyone know what the difference is or why the "blue dyes" are not accurate?
