I tested using blue and pink dye tests before af was due, which was the 8th of this month and got all positives. Now af is late and I'm getting negatives. I read all 9 tests I took within the 2 to 3 minute waiting period and kept staring up until the 10 minute time frame. May I still be pregnant? Once I found out I did increase my fluid intake. Maybe too much water in my urine and it's still early? I've been ttc for a year as of next month so I'm praying this is my rainbow baby! Any thoughts? Has this happened to anyone else?
