Hi Julie

You are doing great. The fact that the stips show trace to medium means that you are well into ketosis. You want to make the same mistake that many of us do and think we should be aiming for the purple colour. The answer is we should not be as this tends to mean we are dehydrated and not drinking enough fluids. So stop worrying about the colour of the strips, you are in ketosis and hopefully the pounds will be slipping away too.
