High reading for first time

33w9d – doctors have been going back and forth about a GD diagnosis for me. I’ve been tracking at home for two weeks (testing four times per day) and have only been above 130 one hour post-meal once. Today, I went to the office and ate less than I normally would during the course of a day (I really just had breakfast and a snack). This evening, went out for dinner and had 1.5 dinner rolls with butter, two side salads, and a grilled chicken breast. My post dinner reading was 157! Could it be from not eating enough throughout the day? Or have I turned a corner and numbers are going to be harder to control now?
