Pink test too?

Caitlin • I`m a married 30 y/o high school digital integration specialist. My husband and I welcomed our rainbow baby into the world 1/2017 and are excited to prepare to expand our family in the next few months.
I've seen a few things saying pink tests are a bit more reliable than blue dye tests. I'm trying to decide if I should take a pink dye test tomorrow. Any advice or info on this situation?
