Hi thanks for contacting HCM...
You have not mentioned any of your report ....
You have thyroid issues and weight gain ...
And not able to conceive ...
First of all your following report needed for more comments .....
-TSH
-T3
-T4 (free t4 )
Based on this report we can reach up to diagnosis like.......
1.Primary hypothyroid or
2.Secondary or tertiary hypothyroid
In primary hypothyroid thyroid itself affected with high TSH and low t4 .For which
levothyroxine drug prescribed ...Dose based on
tsh level ...
Second in secondary or tertiary hypothyroid pituitary and
hypothalamus defect there that should be corrected...
Hypothyroid can sometime lead
infertility ...
But if with drugs TSH level maintained between 2 to 3 than chance of conception more ..
Consult endocrinologist in your state for this ....
Hope I have solved your concern
