Abnormal Labs?

Hello! 25F, 170 lbs, active on my feet 4-5 days a week for work. Went for a physical exam to discuss symptoms of extreme fatigue, daytime sleepiness, joint pain/stiffness (especially in the AM), chronic headaches and most recently having trouble moving my lower body after sitting for a period of time. Occasional numbness and tingling in my arms and legs and what seems to be Raynauds.

I have had very tiring, almost debilitating heavy periods for most of my life, but in the past couple of years the fatigue has been more prevalent even when I’m not menstruating.

Labwork came back with these abnormal results:

Ferritin 13 (dropped from 15 almost a year ago), Iron Saturation 12 (dropped from 33), Iron stable but dropped from 118 to 42, Cortisol low at 5, Vitamin D 25.8 and Positive ANA 1:80/Speckled pattern.

Thyroid normal, hormones normal, lipid panel normal, no signs of diabetes. As a child I had an episode where the lymph node on the left side of my jaw swelled and ever since then I have had discomfort/pain/fullness in my upper left abdomen behind my ribs. There was evidence of spleenomegaly on ultrasound. Lately it has been a lot more uncomfortable.

Trying to make sense of these lab results before meeting again with my PCP? Trying to improve my diet/lifestyle, but its hard when my body just doesn’t feel too good. Thanks!
