My period is three days late. I took a test today and it came back positive. I took two tests shortly afterwards and they both came back negative. They were clearblue digital pregnancy tests. Could this just have been a false positive test and what should I do. Ive been crampy and urinating frequently and no period.

It is really too early to test, Best results are 10 days to 14 days after missed period.

With that said, the best results are first thing in the morning when you wake up. Latter into the day you will have more Negative or incorrect readings.

Since you got a positive reading, that means that you are pregnant, time to go to the doctor for blood test to confirm and start making baby plans
