Hello. The doctor looked at the T4 which was 13.7 (normal range written as 4.5-12.0) and TSH was 2.991 range written as (range 0.450-4.500) My Thyroid Peroxidase was 69 (range 0-34).

He diagnosed me as Hashimoto and said my T4 was high due to birth control and said he doesn't want to put me on any medication. I always feel so tired and have difficulties telling stories or having conversations with people because I forget what I am saying or sometimes doing. I have such a hard time concentrating on anything. I have been in and out of depression all year. This isn't like me and made me go to the doctor back in October because I swore something was wrong with me. My blood work came back fine. My doctor nor I suspected any thyroid problems but he did check my tsh which was 1.070. I didn't suspect any thyroid problems until I found a lump on it in November which started the chain of events that lead to my doctor diagnosing me as Hashimoto and doing a biopsy on my nodules.

I guess my question is..My T4 being slightly out of range could that still cause all my symptoms I just listed? Is it all in my head? Could it be due to birth control (Im on Yaz)?
