hello chandna,it's good to learn that you are taking care of yourself.
if your b.s was previously o.k. with the same dosage of insulin
.then it,s most likely that you are either not following dietary restriction or that you are suffering from some kind of infection or stress
please consult a doctor and go through routine tests like hemogram ,urine etc.
increase your blood glucose
monitoring and take extra units of insulin(increase 2 units at a time),till you acheive your normal b.s.level.thanks
