Cycle predictions depend on patterns that may change or disappear during irregular cycles, hormonal contraception, hormone therapy, fertility treatment, pregnancy, and the months after pregnancy. In these situations, showing fewer insights can be more responsible than presenting a complete Cycle Ring with false confidence.

AIVELA may keep the normal experience, provide a limited experience, or pause predictions according to the status you confirm. Your previous confirmed records remain saved, and the App never uses a prediction as a medical conclusion.

Some life stages need a different question

During treatment or reproductive changes, a familiar cycle display may no longer fit the situation. A limited or paused estimate can be the honest response. Keeping relevant status current helps, but care decisions belong with appropriate professional guidance. You do not need a complete-looking prediction to deserve attention to your experience.

If your cycles are irregular

Cycle length can vary for many reasons, and a prediction may move as new information arrives. You can still log actual period starts and ends, view confirmed history, and follow your temperature trend when available.

Keep these expectations in mind:

• the next expected period may change more than it does for someone with a consistent pattern;
• an estimated phase may not match symptoms or bleeding on every day;
• a predicted date that passes does not become a confirmed period;
• if current predictions run out, AIVELA asks for a new log or ring synchronization instead of extending the calendar by assumption.

Cycle Tracking describes your recorded pattern. It cannot decide whether variation is medically normal or explain why it occurred. If periods become newly irregular, bleeding changes substantially, or the pattern concerns you, speak with a qualified healthcare professional.

Hormonal contraception and other hormone treatment

Hormonal contraception and hormone treatment can change ovulation, bleeding, and the temperature pattern that ordinary cycle-phase estimates expect. Different methods can affect people differently.

When you select hormonal contraception, hormone replacement therapy, another hormone treatment, or “Prefer not to say,” AIVELA provides a more limited Cycle Tracking experience. Depending on the information available, you may still be able to:

• log periods or bleeding;
• see Cycle Day after a confirmed start;
• view an expected next period when a valid prediction remains;
• review Cycle History and temperature trends.

The App does not show ovulation-related language, Cycle Phase, or cycle-length and variability baselines in this limited state. This is a product-confidence boundary, not a statement about whether you ovulate or whether a treatment is working.

Never use an AIVELA phase or temperature trend to change contraception or hormone medication. Follow the instructions for your method and advice from your healthcare professional.

During fertility treatment

Active fertility treatment can intentionally alter hormones, cycle timing, and temperature patterns. AIVELA therefore pauses cycle predictions during treatment.

Your earlier Cycle History remains available, and you can retain appropriate period or bleeding records. When treatment ends, update your status in the App before expecting ordinary phase estimates to resume.

AIVELA Cycle Tracking is not designed to time fertility medication, procedures, intercourse, testing, or clinical monitoring. Use the schedule and measurements provided by your fertility-care team.

During pregnancy

When you confirm that you are pregnant, Cycle Tracking pauses. The normal Cycle Ring, Cycle Phase, next-period prediction, ovulation-related prediction, reminders, and cycle temperature baseline are hidden. Your previous confirmed history is preserved.

AIVELA cannot confirm pregnancy. If pregnancy is possible, use an appropriate pregnancy test and medical guidance rather than waiting for a temperature pattern or missed-period prediction.

Cycle Tracking is not prenatal monitoring and cannot assess pregnancy health. Contact your maternity-care professional about symptoms, medicines, activity, or any concern during pregnancy.

After pregnancy

When you tell AIVELA that pregnancy has ended, Cycle Tracking moves into a waiting state rather than immediately rebuilding a normal predicted cycle. Your body may take time to establish a new pattern, and feeding, sleep disruption, hormones, medication, and recovery can all affect what the ring observes.

Log the next real period when it begins. That confirmed start gives AIVELA an honest new reference point. Predictions should not be based on guessing when your cycle “ought” to return.

Importantly, ovulation can happen before the first postpartum period. A paused or unavailable AIVELA prediction is not contraception and cannot tell you whether pregnancy is possible. Use a recognized birth-control method and professional guidance if avoiding pregnancy matters to you.

Keep your status current

Update Cycle Tracking settings when you:

• start or stop hormonal contraception or another hormone treatment;
• begin or end fertility treatment;
• become pregnant or a pregnancy ends;
• are ready to log the first period after pregnancy.

Do not change a status merely to make more phases appear. The limited and paused experiences exist because those phases may not be interpretable in the usual way.

If you prefer not to disclose hormone status, AIVELA limits the experience rather than infer sensitive information from your data. Information about hormones, fertility treatment, pregnancy, and bleeding is sensitive; review the App's privacy controls and remove manual records you no longer want to keep where supported.

Never use Cycle Tracking for these decisions

Regardless of mode, AIVELA Cycle Tracking must not be used to:

• prevent pregnancy or identify “safe” days for unprotected sex;
• decide when conception is most likely;
• confirm ovulation, pregnancy, miscarriage, menopause, or a hormone condition;
• determine whether contraception, fertility treatment, or hormone therapy is working;
• explain unusual bleeding, pain, or other symptoms;
• replace professional reproductive healthcare.

Seek medical care for severe pain, very heavy bleeding, concerning pregnancy symptoms, or other urgent issues. For new or persistent cycle changes, discuss the pattern with a qualified healthcare professional even if the App does not flag it.

When the usual assumptions do not fit, less prediction is often the more honest experience.
