Guidance Please

I have been on keto for one week today. I have used the Carb Manager app and have stuck to the keto guidelines strictly. I started testing my ketones with test strips over the weekend. The highest I’ve gotten is about 1.0/1.5. It’s now gone back down to “trace.” I’ve not experienced ketone flu symptoms. I’m 40 years old, 5’0” and 193 lbs. I am an attorney so I don’t get much exercise at work, but I have a 5 year old son and 3 year old daughter so I run after them evenings and weekends. My husband is doing keto with me, and his ketones keep going up. Can anyone give me any advice of what I might be doing wrong? I can answer more specific questions as you have them... thank you so much I’m advance; I’m becoming frustrated.
