Pink or blue dye?

My first pregnancy i never got a positive with the pink dye tests and only with the blue Kroger brand and the digital one. My LO is now almost 9 months old. And i bought the clinical gaurd strips off amazon and they are pink dye. I thought maybe there was a smallll faint line on one today but its honestly to hard to tell and think id be better off going and buying a blue dye test since i know those work for me. I cant base anything off of cycles cuz im EBF and havent had a period yet. Does anyone else respond better to blue dye ??? Also anyone hate the clinical gaurd preg strips?
