Levels?: You don't give levels, but it looks like your question got cut off. All i can say is the correct dosing should put you in a normal range based on blood testing; ironically, many folk feel better when overdosed because they feel they have more energy. Being over corrected (based on blood) is ultimately harmful though, so keep that in mind.

Does not add up: At 46 years of age what prompted you to get infertility evaluation. If your TSH is normal, you may not need adjustment to your dose.
