Negative then positive?!

Question

So i took a blue dye hpt two days ago. At first it was negative. Then a couple hours later it was positive. The next day I took a red dye hpt and it was negative. Today I took a blue dye hpt and it was negative at first then it was positive hours later, this time though the blue line was darker then when I took the blue dye one previously. I know they're supposed to be invalid after 10 mins, but if my lines have color why are they taking so long to show up? Does this mean I'm pregnant or not?

Answer

The reason they tell you to read the tests within a few minutes is because if you wait too long as the urine evaporates the dyes can run giving you evaporation lines which are a false positive. Always follow the instructions. Blue dye also tends to show more mistakes so if the pink ones are negative and the blues only show lines after hours then you do not have any positive tests at this point.

Answer

Very early on in pregnancy u had a test be negative then turn positive, they say most of the times there nit valid after that long and it's a evaporation line, but I just kept testing and they eventually became positive, I'm 14+5 now

Answer

Get tested at the doctor

Answer

Sorry but if say you are not.

Answer

I'd wait a few days as those these won't be valid. So text in the next few days and keep testing till a positive comes up within the time frame good luck x
