Hello, I am pregnant and just diagnosed with gestational diabetes. I have been taking my readings for 5 days now, and all have been in the 80 s and 90 s, except one at 110. Today, I haven t don e anything different, and got a reading 2 hours after eating lunch of 142....the only thing I can think of is that my sugar free iced coffee I ordered at 11:00 this morning was not made sugar free....is this reading really high and hurtful?
