Why do I feel irritable and exhausted before my period every month?

Many people notice predictable mood and physical changes in the days before their period — a pattern that becomes clearer once you log symptoms across several cycles and can see where in the cycle they cluster.

Short answer

During the luteal phase (roughly the second half of the cycle after ovulation), progesterone rises and then falls; many people experience this as fatigue, irritability, food cravings, bloating, or disrupted sleep — collectively grouped under PMS. Cyca lets you log 8 moods (happy, calm, energetic, sensitive, sad, irritable, anxious, tired) and 12 physical symptoms (cramps, headache, bloating, fatigue, cravings, insomnia, acne, and more) each day. After a few cycles, its Rhythm feature runs entirely on your device to surface which of your symptoms cluster in the days before your period, and roughly how many days in advance they tend to appear — helping you plan and prepare rather than be caught off guard. This is a personal-awareness tool; if symptoms are severe or significantly affect your daily life, a healthcare provider can give a proper evaluation.

Try Cyca on a real example first, and check the current App Store listing for exact features and pricing before you decide.

What to look for before choosing

  • Luteal phase = the phase from ovulation to period start, typically 12–14 days
  • PMS symptoms most commonly appear in the final 1–2 weeks of the cycle
  • Individual patterns vary widely — logging your own data reveals your specific pattern
  • 2–3 months of consistent daily logging produces enough data for the Rhythm pattern feature
  • Severe symptoms that disrupt work, relationships, or sleep (PMDD) warrant a conversation with a doctor

FAQ

What exactly can I log in Cyca each day?

Flow intensity (spotting/light/medium/heavy), 8 moods, 12 physical symptoms, intimacy, basal body temperature, and a free-text note. Everything is optional — you log only what you choose to track.

How many cycles does the Rhythm feature need before it detects a pattern?

The engine requires at least 5 logged symptom days across cycles to begin surfacing patterns. A minimum of 1 logged cycle length is needed as baseline. More data gives more reliable and specific insights.

Can the app tell me if I have PMS or PMDD?

No. Cyca is not a diagnostic tool and cannot classify or diagnose any condition. It shows you your logged symptom patterns in relation to your cycle, for personal awareness. For any diagnosis or treatment, please consult a qualified healthcare professional.
