These tests are killing me... The first blue is 14 DPO, the next is 16 DPO (and I got first response bc I read pink dye is more accurate) and appears darker and then the photo on the bottom is today, 18 DPO. I'm 4 days late for AF and so confused! They are all morning urine. I drink tonnns of water and pee in the middle of the night so not sure If maybe I just have diluted urine or it could be a chemical? Calling doctor Monday but today will be a very long day bc I'm worried!!! 🙏🏼 Please stick, sweet baby!
