Hyperglycemia after main food third day

Good, I am 43 years old and diabetes 1 for almost a year and a half.My analytics until now, with the three glycolisadas of the three analytics below seven.
The thing is that I have been practically three days of confinement with values ​​within the limits except hyperglycemia after food, being today greater than 300. The rest more or less although this tomorrow seemed a little high, 170 for what I had dinner.
My guideline is from Toujeo from 16 to 4 pm and Novo Rapid in meals.
In the slow injection today at 4 pm, I change to the new pencil because I can't think of another.
Thank you

If you exercised before and have been locked at home for three days, I think that is what is affecting and changing the factors.It is complicated.You will have to increase quickly and slowly.

Cheer up

Ok, thanks, it must be that
