Antibodies and other blood results, help?

Hi, I'm new here and looking for some insight.

I'm 27 and have had some symptoms of hypothyroid for years. 3/4 years ago I had bloods that the doctor just said were normal and never thought about it again, although I know I have those results around here somewhere. Then recently had my thyroid checked as part of recurrent miscarriage testing but my consultant only checked my TSH which I was told was normal and nothing else. At this point I decided to dig a little deeper on my own and went private for a more detailed check including antibodies. These were positive although not far out of range, however all the function tests are normal, FT4 is borderline low but not sure what anything means so hoping someone with more experience can give me an opinion. Here are my results:

TSH - 2.09 mIU/L [0.27 - 4.20]
FT4 - 12.46 pmol/L [12.00 - 22.00]
T4 - 92.0 nmol/L [59.00 - 154.00]
FT3 - 4.85 pmol/L [3.10 - 6.80]

Thyroglobulin antibody - 127.300 IU/mL [0.00 - 115.00]
Thyroid peroxidase antibodies - 35.32 IU/mL [0.00 - 34.00]

The thyroid check included a few other bits too:

Vitamin B12 - 257 pmol/L [140.00 - 724.00]
Folate - >19.98 ug/L [2.91 - 50.00]
Ferritin - 45.09 ug/L [13.00 - 150.00]

The B12 seems a bit on the low side so I'll be getting some supplements, but not sure if anything else could do with a boost. Any thoughts about the whole thing? Should I just accept that nothing is out of range enough to be treated?

Thank you in advance
