I am 31years old. My TSH level is 3.57ulu/ml. Then I take Clomid (clomiphene) 100g 5 days. (after date of 6th my periods) t4-1.30ng/dl. Then what can I do?

Clomid (clomiphene) and testing. I agree your thyroid is under control. It is important that it is so, but unlikey to affect your fertilty once fixed. You should concentrate on two things. If your cycles are irregular you should give Clomid (clomiphene) a few months to work. Your doctor will decide how to manage that. You also should make sure your doc does a work up to rule out other causes (sperm issues, tubal blockage etc).
Thyroid. Thyroid testing seems to be normal based on your reported values as long as T4 is labeled as free t4. Follow your doctor's instructions on Clomid (clomiphene) use.
