About a year ago I was diagnosed with borderline hypothyroidism but my doctor didn't feel it was necessary to prescribe anything. I did a follow-up test about 6 months letter and get the same results and response from the doctor. We recently started trying for a baby and I had a early miscarriage in Dec and my fertility clinic recommend that I have my thyroid test again. I got my results back last week and my doctor said they are normal but my serum free T4 level is at the low end of normal 12.5 (their range is 10.30-24.50) and my serum TSH level is on the higher side of normal at 4.8 (their range is 0.30-5.5).
Would you recommend me getting any other tests or pushing the doctor to prescribe medication?
If we weren't trying to conceive, I would probably accept the 'normal' diagnosis but I'm 37 and not getting any younger so I want to make sure my body is working with me rather than against me
