Predictions Seem Wrong
Learn why predictions may be off and how to improve their accuracy over time.
Key Insight
Lova needs at least 3 complete cycles of data to make accurate predictions. The more cycles logged, the better the predictions become. If you've just started using Lova, give it time to learn your patterns.
1 How Predictions Work
Lova uses your logged cycle data to calculate predictions. The algorithm analyzes:
- Your average cycle length
- Variation between cycles
- Recent cycle patterns
- Logged symptoms (if tracked)
ℹ️
Privacy Note
All prediction calculations happen on your device. Your cycle data never leaves your phone.
2 Common Causes of Inaccurate Predictions
1 Not enough cycle history (need at least 3 complete cycles)
2 Irregular cycles due to stress, illness, or lifestyle changes
3 Recently started or stopped hormonal contraception
4 Perimenopause or other hormonal transitions
5 Inconsistent period start date logging
3 Factors Affecting Accuracy
| Factor | Impact | Minimum Needed |
|---|---|---|
| Cycle history length | More months = better predictions | 3+ cycles |
| Consistent logging | Regular data improves accuracy | Daily entries |
| Symptom tracking | Additional data points help | Optional but helpful |
| Life changes | Stress, travel affect cycles | Note in journal |
4 How to Improve Accuracy
- 1 Log period start dates accurately - Mark the first day of bleeding, not spotting
- 2 Track consistently - Log data daily or at least mark period start/end
- 3 Note life changes - Use the journal to record stress, travel, illness
- 4 Be patient - Accuracy improves with each completed cycle
5 When Predictions May Not Apply
Some situations make cycle prediction inherently difficult:
Hormonal contraception
Birth control regulates cycles artificially
Postpartum/breastfeeding
Cycles may be irregular or absent
PCOS or other conditions
Can cause highly variable cycles
Perimenopause
Natural cycle changes occur

Still Have Questions?
If predictions remain inaccurate after 3+ cycles:
- Check that period start dates are logged correctly
- Review cycle history for any missing entries
- Consider consulting a healthcare provider if cycles are very irregular
