its far better to be light pink than any other shade girls, this indicates that you are in ketosis, which is where we want to be, but also that the hydration levels are low.........the darker the pink, the more dehydrated you are.
the truth is though, if you are sticking to the diet 100% then you will be in ketosis after a few days (varies from person to person), there is no need to doubt or test, and definitely try not to get hung up on the testing stix.....it will work!!!
