Hi everyone. I'm 30 weeks and could really use some shared experience and advice. Trying to keep this short.

The story so far:

• Diagnosed with GD at 28 weeks, values were already high
• Started insulin a week ago: 3 units, 3x a day, 20 mins before each meal
• Fasting average ~100 (no insulin for fasting yet)
• 1-hour post-meal average ~150 — doctor wants me under 140
• So even on insulin, post-meal numbers aren't budging

Yesterday's ultrasound (this is what's scaring me):

• Amniotic fluid just above the upper limit
• Umbilical cord shows some resistance to blood flow, PI 1.29 at 97th percentile
• Doctor said it could be linked to the high blood sugar
• Baby's weight (1680g) and growth are normal so far

Today's readings:

• Pre-lunch (after insulin): 71 — felt low
• 1 hr after lunch: 149
• 2 hr after lunch: 143

My diet (~100–130g carbs/day):

• Breakfast: 30g oats, nuts/seeds, 2 egg whites, ¼ avocado
• Lunch: 40g quinoa (uncooked), 2 whole eggs, lots of veggies, ¼ avocado, small portion of lentil curry
• Snack: chickpea salad
• Dinner: 60g ragi (finger millet), chicken, veggies
• Other snacks rotated in: wheat crackers, cottage cheese, kiwi, pistachios, yogurt, peanut butter
• 20-min walk after every meal

What I'd love help with:

1. Anyone been through GD + high amniotic fluid + umbilical cord resistance? How did it progress?
2. If you were on insulin and your post-meal numbers still wouldn't come down — what finally moved the needle? Insulin dose increase, food swaps, timing tweaks?
3. Is anything in my meals an obvious problem? The oats and quinoa feel "safe" on paper but I'm starting to wonder.

Thank you so much in advance  Feeling pretty anxious and any input helps.
