Pink vs blue

Ash • Married and ttc baby #1 ♡
So I always see people on here stating how blue dye tests are notorious for false positives and that they aren't reliable and you should use a pink one and la la la. Well I was doing a lot of research today while I'm bed ridden due to this bug and found that that's kinda false. It has been scientifically proven that that's not entirely true regarding blue dye tests. They said that it is possible to get a false positive on ALL tests, including pink dye ones and blue ones have been known to be the most accurate and most used hpt. Most false positives end in a chemical pregnancy. I'll try to find the research again and post it for everyone. But food for thought.
