i have heard you have to stop supplements for 3+ months before getting tested to have an accurate result..
first- is this true? second- is there another test i could do where this won’t be a problem… i have to drink boost plus shakes daily bc im very underweight but they have b12 in them

my hemoglobin (13), hematocrit (37), iron (120), binding capacity (364), and saturation (33%) are all good numbers…. hemoglobin and hematocrit are going towards the lower end and my rbc (4.2) is on the line but all still in range.
my doctor says my numbers are great for someone that hardly eats meat. but i feel awful. palpitations/tachycardia, excercise intolerance, heat intolerance, no appetite, extreme anxiety, shortness of breath, headaches, lightheadedness, i can’t remember anything or just think straight to the point where it’s scaring me. my ferritin is 10.
i’m just not sure only having low ferritin could cause this? if my body was rlly starved of iron wouldn’t my other numbers be reflecting that better? to my understanding oxygen is getting around my body just fine… so i shouldn’t be having symptoms right? this is so frustrating idk what to do 😔

i’m not sure where else to post this lol but is this normal? i usually rest around 80-85bpm but during my luteal phase i’m anywhere between 95-100 and im very aware of it and it’s exhausting and anxiety inducing. my temp also goes up by 1°F and im constantly hot and cold at the same time. i wouldn’t describe it as clammy either… but ill be sweating and have goosebumps. internally i feel hot but externally im freezing.. does that make sense?? i never used to have this problem until the last year or two.
