Interpret thyroid labs?
So here is what I got
TSH : 0.673
Free T3: 2.45
Free T4: 1.3
is that normal or not?

I don't know but I'll be sure to let you know once I get the other tests done.
Thank you so much for your help :)

There are different causes of microcytic hypochromic anemia; do you know the cause of yours? Iron deficiency is the most common.
You MCV indicates that your red blood cells are smaller than normal, which is consistent with iron deficiency anemia.
Will be interested to see antibody and vitamin B-12 tests.

I have mild microcytic hypochromic anaemia.
These are the results:
MCV: 73.9 ref. (80-100)
RDW-CV: 14.8% ref. (11.5-14.5)
RDW-SD: 39.9 fL ref. (35-56)

Yes, do get the antibody tests done and be sure to test vitamin B-12, as well, because low levels would indicate Pernicious Anemia, which can also cause the swollen tongue/tooth marks on the tongue.
True, your FSH and LH are not normal, but they can be elevated just prior to ovulation.
What type of anemia do you have? Check your lab report for tests called RDW and MCV... if it's on there, what are the results and reference ranges?

Thank you so much for your reply. I'll get tested for the antibodies soon.
The teeth marks are only on the sides not all the way around.
My doctor said that it was not PCOS but that my FSH (4.6 mIU/mL) and LH (5.6 mIU/mL) are not normal either.
the cbc shows that I have mild anaemia.
The bump is on the upper right side of my head, it's been there for over a year.

Your thyroid levels don't really look bad.
Rule of thumb for FT4 is to be around mid range; yours is actually at 52%. Rule of thumb for FT3 is upper half to upper third of range; yours is 51%.
Typically, the "rule of thumbs" are for those of us on thyroid med, because we don't have "hormones on demand" like people with a working thyroid.
That said, your symptoms lean toward hypo, so the next thing I'd recommend is to get tested for thyroid antibodies to determine whether or not you have Hashimoto's Thyroiditis. Hashimoto's is an autoimmune disease in which the body sees the thyroid as "foreign" and produces antibodies to destroy it. Hashi's is the most common cause of hypothyroidism in the developed world. It's not unusual for symptoms to precede lab indications when one has Hashimoto's...
The antibodies are continually destroying healthy thyroid tissue and as this happens your thyroid function diminishes... this can cause symptoms long before FT3 and FT4 go out of range, in fact, they may never go out of range.
It is relevant that you have teeth marks on your tongue... swollen tongue that leave teeth marks can be a sign of hypothyroidism, but it can also be a sign of Pernicious Anemia. Are the teeth marks all the way around the tongue?
Fatigue can also be a symptom of either hypothyroidism or Pernicious Anemia. I have both Hashi/hypo and PA... For me, the fatigue from PA was much more severe than that caused by being hypo... low iron can also cause fatigue.
The hair loss and irregular periods could certainly be from being hypo, but they can also be caused by other things.
I'd recommend that you get tested for vitamin B-12 and ferritin, to see if either of those could be a cause for your fatigue; additionally, iron is necessary for the metabolism of thyroid hormones.
If you've been tested for PCOS, I assume that reproductive hormones were all tested? All hormones have to be balanced or one won't feel right.
Where is the really hard bump on your head that won't go away? How long has it been there?

Oh sorry here are the reference ranges: :)
-TSH: 0.673 ref.(0.38-4.70 uIU/mL)
-Free T3: 2.45 ref.(1.45-3.4 pg/mL)
-Free T4: 1.3 ref. (0.71-1.85 ng/dL)
I haven't been diagnosed with a thyroid problem and my doctor says my ranges are normal but I believe something is wrong :/
here are my symptoms
-fatigue
-hair loss
-my hair used to be shiny now its very dry.
-irregular periods
-I haven't gained weight but I can't seem to lose it either.
(I don't know if this is relevant or not but I have teeth marks on my tongue? and a really hard bump on my head that won't go away.)
One doctor told me it might be PCOS but that was normal too.
I'm only 21 but I constantly feel tired.

Whenever we try to assess test results, we need to know their reference ranges shown on the lab report. That is because test results and ranges vary from lab to lab, so need both. Beyond that the ranges are far too broad for all levels to be functional for all hypo patients. Everyone is different and different levels may be required to relieve symptoms. So, please tell us about any symptoms you have. Also, have you been diagnosed as having a thyroid problem? If so, are you taking thyroid med? And if taking med, what brand and daily dosage?

What are the reference ranges for the FT3 and FT4? Ranges vary lab to lab and have to come from your own report.
Have you been diagnosed with a thyroid condition? Are you currently on a thyroid medication? If so, which one, what dosage?
Do you have symptoms of a thyroid condition? If so, what are they?
