[/INST] Hi Welcome to Chat Doctor Your TSH level done in dec-12 is on higher side. When you are trying to conceive TSH levels should be maintained between 0.5- 3 mid/ml. In your case you should start taking Thyroxine after consulting your doctor. Hypothyroidism is known to cause infertility by causing ovulatory dysfunction. Hope you have been examined thoroughly and other factors leading to infertility have been ruled out. Try to lose weight by exercise and diet.  All the best </s>
