Hey, it absolutely happens, when hormones come into play sugar levels go erratic.
I’m 14 years and have been diagnosed since the age of 5. I too go through periods of insulin resistance, in similar situations as you.
I guess in those times, I just control my diet and limit my carbohydrate intake more, as to not fuel any hyperglycemic incidences. I try to exercise more too, trying to control my blood sugar levels.
Taking medication and playing my part. Guess in situations like these, we just have to stay strong and keep going!!
