Crazy blood sugars?!

I am a type one diabetic. I'm on an insulin pump and have a continuous glucose monitor so I am usually able to keep really good control of my sugars. Over the weekend my blood sugars have been ridiculously high. Even after I bolus for the correct amount of carbs they shoot up and later fall rapidly. I know that literally anything can affect my blood sugars but as someone who generally has good numbers this is really different for me. Could this be a early sign? I am about 10 dpo and realize that is still early but I have had a few other symptoms as well. Any other diabetics have this as an early sign?
