In general, the target TSH for women trying to conceive when they have a history of hypothyroidism/Hashimoto's (which is what your labs suggest) is 0.3-2.0.  From what you post, the TSH of 1.07 would be appropriate to try to conceive but do need to followup closely with your doctor.  I do not think that your other symptoms are likely related to thyroid medication but please discuss these with your doctor as well
