Am I doing this right?

So, I tried starting keto about 4 days ago, but I haven't noticed any sort of flu, urine change, or any metallic taste in my mouth. I've eaten nothing but bacon, eggs, beef sticks, cheese, salad(ranch dressing used sparingly), steak, pork chops and water. Also have not noticed a change in the way my body feels at all. Am I missing something, doing something wrong? Edit: Just used a test strip, showing a trace of ketones in my body!
