Hey jp-

I am not familiar with those type of ketostix, so I cannot help you there. Usually the ones I have seen have a beige pad that changes to purple if you are in ketosis. However, there are other indications that you are in ketosis:

Metalic taste in the mouth-often bad breath
smelly urine
a feeling of heat, especially at night

Pork is OK, and so is cheese-but cheese should be limited to 4 oz a day when in induction. That only lasts two weeks. You really need to get your veggies in as well-most of your carbs are supposed to come from allowed veggies like salads and anything pretty much green.

Have you been to the Atkins website? It breaks down each of the stages pretty well.
