Blood glucose levels

My diabetologist asked me to take readings for 2 weeks.

1st week-

Fasting-108

1hour after breakfast-180

1hour after lunch-130

1hour after dinner-131

2ndweek

Fasting-105

1hour after breakfast-162

1hour lunch-116

1hour dinner-115

I have been religiously walking since I was diagnosed with GD. I know that fastings are on the higher side. But what about the readings after breakfast? Does 1 hour after breakfast upper limit is 180 or 140? I am totally confused. I have limited my diet,cut off my carbs completely. I have worried about this so long😓😓
