When you "just feel off", it's hard to tell why. Let's cover the essentials in small steps and see where the cycle fits. A pointer, not a diagnosis.
What bothers you most?
Two short questions to rule out anything urgent — then we can relax a bit.
Is your temperature above 38°C (100.4°F)?
Have you fainted or felt about to faint?
How long has it lasted?
How you feel often cycles with your cycle: many feel low and irritable before a period, and heavy periods can cause fatigue through iron loss.
Do you notice a cycle link — usually worse before or during your period?
Does it disrupt normal life (work, study, sleep)?

Worth seeing a clinician
Long or heavy malaise is a reason to check simple things: blood count, iron, thyroid. Quick tests that often explain everything.
What you can do
- See a GP or gynecologist and describe how long it's lasted
- Ask to check hemoglobin and ferritin
- Log how you feel in HeySis — the doctor sees the day-by-day picture
nothing worrying here
Looks like cycle swings
How you feel may be linked to your cycle, but this check can't tell the cause. Rest and keep an eye on your symptoms.
What you can do
- Sleep, water, food by appetite — no heroics today
- Log mood and fatigue in HeySis for a couple of cycles
- If it worsens or passes two weeks — see a clinician
This is a hint, not a diagnosis. If you're unsure, a doctor will know best.
