Brief Answer:
Weight loss of 13kg may not be due to Metaformin alone.

Detailed Answer:
Hi,

Thanks for your question.
Noted your concern.

Metformin usually used in PCOD to reduce insulin resistance (to decrease insulin requirement of body).

It is usually considered as weight neutral.
Weight loss of 13kg may not be attributed to use of Metformin alone.

There might be other causes like
- Diet
- Exercise.
- Good control of hypothyroidism.

If you continue diet restrictions, regular exercise and compliance with thyroid medicine there are very less chance of weight gain after stopping Metformin.

Metaformin definitely interfere with HbA1C value.

But HbA1C value in such a cases gives much more information -

1) Blood sugar levels over a period of 3 to 4 months.
2) Whether to continue metformin or not.
3) If HbA1C is out of range even with use of metformin it will confirm diagnosis of Diabetes. And accordingly appropriate decision regarding increase in medications should be considered.

Rather than thinking about future risk of Diabetes it's better to focus on further weight reduction with diet restrictions & regular exercise, with regular follow ups with your treating endocrinologist or gynecologist.

Hope this helps you.
