Aww sis, I totally understand your worry, gestational diabetes is really stressful talaga, but please reach out to your OB or endocrinologist right away kung hindi na niya alam, okay? Hindi ko pwedeng mag-suggest ng specific tips kasi this really needs professional guidance para safe sa baby mo.
A few of us moms have gone through this, and honestly ang best thing we did was follow exactly what our doctors said, because every pregnancy is different, at ang monitoring mo 6x a day shows your doctor is on top of it na. Huwag mag-skip ng pagkain out of fear, kasi that can be risky din; instead, work closely with your OB or a dietitian na kayang mag-adjust ng meal plan mo based on your readings.
You're doing great by monitoring closely, just let the experts guide you from here, ha? Kaya mo yan, and your baby needs you healthy. Sending strength!
