Your periods being regular and lasting 2 days can still be normal. A usual period lasts about 2 to 7 days, and regular timing is reassuring. A shorter flow alone does not mean PCOS or infertility. The pattern should be reviewed if flow has become progressively lighter, cycles become irregular, or there are symptoms such as weight change, acne/excess facial hair, nipple discharge, headaches/vision changes, or difficulty conceiving. ACOG menstrual guidance

What the blood report shows

Finding	Result	Meaning
Hemoglobin	12.0 g/dL	Lower end of normal
Hematocrit	34.7%	Mildly low
MCV	79.6 fL	Low, meaning red cells are smaller than usual
Serum iron	128.9 µg/dL	Normal, but this alone does not rule out iron deficiency
Thyroid tests	TSH 1.73, FT3/FT4 normal	Thyroid dysfunction is unlikely to be the cause
Vitamin D	7.73 ng/mL	Severe vitamin D deficiency
Fasting glucose/HbA1c	Normal	No evidence of diabetes
Kidney/liver tests	Normal	Reassuring

Main interpretations

Severe vitamin D deficiency needs treatment
- A 25-OH vitamin D level of 7.73 ng/mL is in the deficient range.
- It may contribute to fatigue, muscle aches, low mood, bone discomfort, and can coexist with diffuse hair shedding, though it is not always the sole cause.
- Please see a physician for a replacement plan. Many clinicians use a higher-dose vitamin D course followed by maintenance, but the exact dose and duration should be individualized. Do not take very high doses long term without medical advice.
Possible early iron deficiency or thalassemia trait
- Low MCV plus slightly low hematocrit suggests microcytosis.
- A normal one-time serum iron level does not accurately show iron stores, and it can vary with diet and timing.
- Iron deficiency is a recognized potential contributor to diffuse hair loss; thyroid disease and other types of alopecia are also considered in the evaluation. Fitzpatrick's Dermatology, p. 1577.
- Another possibility, especially if microcytosis persists despite normal iron stores or there is a family history, is thalassemia trait. This is not diagnosed from this CBC alone.
Thyroid is normal
- Your normal TSH, free T3, and free T4 make hypothyroidism or hyperthyroidism less likely as the explanation for dry lips, hair loss, or short menstrual flow.

Tests to discuss with a physician

For the hair fall and microcytosis, ask for:

Serum ferritin - most useful initial test for iron stores
TIBC/transferrin saturation
Peripheral blood smear and repeat CBC
Vitamin B12 and folate
Hemoglobin electrophoresis/HPLC, particularly if ferritin is normal or there is family history of anemia/thalassemia
If hair fall is significant: dermatologist scalp examination to distinguish diffuse shedding (telogen effluvium), female-pattern hair loss, traction-related hair loss, dandruff/scalp inflammation, or alopecia areata.

The mildly elevated absolute lymphocyte count is usually nonspecific, often occurring after a recent viral illness. Repeat CBC during follow-up is reasonable, especially if it persists or you have fever, swollen lymph nodes, recurrent infections, or unexplained weight loss.

About dry lips

Severe lip dryness is often due to irritant/contact cheilitis, lip licking, dehydration, dry climate, toothpaste or cosmetic reactions, or less often nutritional deficiencies.

For now:

Use plain petroleum jelly frequently, especially before sleep.
Avoid lip licking, menthol/camphor/fragranced balms, matte lip products, and lip scrubs.
Use a gentle toothpaste without strong flavoring if irritation seems related.
Ensure adequate fluid and protein intake.
If there are cracks at the mouth corners, recurrent sores, swelling, rash, or no improvement after 2 to 3 weeks, see a dermatologist. Angular cheilitis can sometimes need specific treatment.

Hair-care advice while being evaluated

Avoid tight hairstyles, frequent heat styling, chemical straightening, and vigorous oil massage/combing.
Eat sufficient protein daily, with iron-containing foods such as lentils/beans, greens, eggs, meat or fish if eaten, and pair plant iron sources with vitamin C.
Do not start iron tablets based only on this report. First obtain ferritin and iron studies, because low MCV can also occur with thalassemia trait.
Avoid high-dose biotin supplements before blood tests, as they can interfere with some lab assays and are not reliably helpful unless a true deficiency exists.

Seek earlier medical review if

hair loss becomes patchy or leaves visible bald areas
new irregular or absent periods occur
severe fatigue, breathlessness, palpitations, dizziness, bone pain, or muscle weakness develops
you are trying to conceive or might be pregnant.

The two most actionable items are: treat the severe vitamin D deficiency under medical guidance and check ferritin/TIBC before taking iron.
