Thanks for using Healthcaremagic,
After going through your history, you have Hypothyroidism
and delivered 6 months back.
Your weight gain is related to Hypothyroid and calories intake and lack of physical exercise and not due to Copper T.
Sometimes weight gain after copper T insertion is due to reduction in anxiety
so please do not worry and take care of diet in terms of calories and nutrition.
Take up some form of exercise and yoga
If you reduce 500 Kcal from your diet and increase caloric expenditure the deficit in 2 week is 7000 Kcal results in weight loss
of 1 Kg.
You should also get your Thyroid function FT3,FT4 and TSH if required dose can be increased.
Hope this helps.

Take care of your health.
