Only getting positives with blue dye pregnancy tests?

so i have like a crazy women taken about 10 tests 4 being blue dye ones all 4 were positive but red dye tests all are negative??? very confused and drained with trying to figure this pregnancy thing out. I first took a walgreen brand blue dye which came out positive right away both did. then 2 ept blue dye tests both started which looked to be positive then finished in the 3 min mark as negative about 8 min after testing both times both tests turned a faint but deff blue positive. I have taken a clearblue digital which was negative dollar store red dye negative and first response red dye negative. but all 4 blue dye were a very clear positive only the ept about 8 min after testing i know i need to wait about 3 days and re test or get a blood test my question is has this ever happened to anybody blue vs red early on in the pregnancy and was preggo? and am i pregnant? UGH so stressful
