hi and welcome to minimins

wonderful site here and am sure you will get lots of support and advise.
ketostix as long as it changes colour then you are in ketosis, if its really deep purple try a bit more water as this can be dehydration but first pee of the morning is when ketones are at there most concentrated, you will find the colour gets lighter as the day goes on as they are more dilute due to the water you drink so dont panic
the hunger, as others have said in ketosis you shouldnt feel physical hunger but your brain is crafty and trys to get you to eat as it is used to you eating. drink more water, read a book, have a bath, go for a walk, it should disappear
