Fasting glucose improved within weeks and my HbA1c barely moved for three months, which I now understand and did not at the time.
The narrow version of the question is why A1C lags the way it does, and what to look at in the meantime if you want to know sooner.
Numbers rather than impressions, if you have them.

Insulin sensitivity test (HOMA-IR) on glycaemic control — arguably the most important metabolic marker most people aren't tracking:
HOMA-IR = (fasting insulin × fasting glucose) ÷ 405
My numbers: Baseline HOMA-IR = 4.9 (insulin resistant) → Current = 1.1 (insulin sensitive)
Anything above 2.0 indicates insulin resistance. The goal is below 1.5. GLP-1 agonists address the root metabolic dysfunction, not just the symptoms. This is why they work so much better than calorie restriction alone.

My labs after 9 months on glycaemic control: A1C 6.1%, fasting glucose 81 mg/dL, fasting insulin 6 uIU/mL. My endo says these are "textbook perfect."
For context, my baseline A1C was 7.7% and fasting glucose was 136 mg/dL. The improvement has been dramatic and consistent.

This matches mine closely enough to be worth saying so out loud. The detail I would add is minor and it is already implied above.
Adding the clinical framing, because it changes how the question reads.
PCOS success story with glycaemic control: as someone with polycystic ovary syndrome, this medication has been transformative beyond weight loss.
After 11 months: periods became regular for the first time in a decade, testosterone levels normalized, acne cleared significantly, and — unexpectedly — my fertility specialist is optimistic about future conception.
GLP-1 agonists address the insulin resistance at the root of PCOS. For PCOS patients, this isn't "just" a weight loss drug — it's treating our underlying metabolic dysfunction.
