Help / confused
About 18 months ago, I had prenatal labs drawn and my A1C was 5.6 and fasting glucose was 99. I realize this is technically in normal but being newly pregnant it was higher than I'd have liked, especially as I had zero blood sugar issues with previous pregnancies and am thin, active, and eat well. I had an early work up with endocrinology and they said to let my OB monitor, and to make a long story short, I had a cluster of a situation and never received the oral glucose tolerance test. My doctor relied on A1C draws, which I thought at the time was a more specific way to monitor me, but I now know means nothing in pregnancy. This is upsetting as we think I had missed gestational diabetes and there have been other sequelae. I am now 11 months post partum and still struggling to regulate my BS. I take 500 mg metformin nightly and my fasting sugar is usually high 90s. I walk 10,000 steps every day. I need to increase resistance training but have other injuries which have prevented me from doing so. Sometimes throughout the day my BS will just rise up to 120-125 without any reason, even if I haven't eaten in several hours. Why? What should my blood sugar be when I'm just up and moving about my day? Why does it rise to like 110 around 10 pm? Sometimes it will drop down to mid 80s after long walks and I keep it under 140-150 with strict diet but I am just so confused at what my targets should be and I don't have a great doctor helping me figure this out. I'm 37F, 5 ft 9 in, 120 pounds. Would love some insight.
