PMS questions and answers
Answers to what people ask about the days before a period: whether PMS is normal, why anxiety spikes, how PMS differs from PMDD, and how Niyora predicts your window and helps you through the moment.
About PMS
Is PMS normal?
Yes. Around 80 percent of women notice premenstrual symptoms in the days before a period, so this is close to universal. When researchers measured hormone levels, women who feel awful before their period had the same levels as women who feel fine. The difference is in how strongly your brain responds to the normal hormonal shift, not in your hormones being wrong.
Why do I feel so anxious before my period?
Your body has a built-in brake on fear that usually works in the background. In the days before your period, as hormones shift, that brake eases off, so a small thing, like a text or a silence, can read as a threat. Your alarm is turned up more sensitive for a few days, and it settles as the shift passes.
Can PMS make you feel like a different person?
It can feel that way, and you are still you underneath it. Before your period the systems that absorb stress and reach for calm run at lower power, so anger lands sharper and a normal load feels like too much. Your real self has not changed. It softens as your body moves past the shift.
How do I calm down before my period?
Your body decides whether you are safe before your mind catches up, so settling your body first works better than arguing with the thought. Slower breath, warmth, and a steady presence help your body feel safe again, and your thinking calms down after it. This is the one-minute regulate step Niyora walks you through.
PMS vs PMDD
What is the difference between PMS and PMDD?
PMS and PMDD sit on the same spectrum. Most women get PMS, which is real but manageable. PMDD is a more severe form that affects about 1.6% to 3.2% of women when confirmed with daily tracking, and 7.7% on a provisional diagnosis, with intense mood symptoms in the premenstrual window that clear once the period starts. PMDD was only recognized as a full medical diagnosis in 2013. If your premenstrual week regularly disrupts your work or relationships, it is worth raising with a doctor.
Is it PMS or depression?
The clearest signal is timing. Premenstrual mood symptoms show up with the hormonal shift before your period and ease within a day or two of it starting, then you have clear weeks. Depression tends to stay steady across the whole month and does not track your cycle. If low mood does not lift after your period, or you never get a clear stretch, that is a reason to talk to a doctor rather than assume it is PMS.
Is premenstrual anxiety or low mood something to worry about?
Premenstrual feelings are a passing hormonal moment, and your body moves through it every cycle. When researchers switched these hormones off the symptoms cleared, and switching them back on brought them back, which shows how tied the feelings are to the shift. What is worth flagging to a doctor is when symptoms are severe, do not ease after your period, or include thoughts of harming yourself. Niyora is a tool for the moment, not a substitute for care.
Using Niyora
How does Niyora work?
Niyora is a private iPhone app for the days before your period. It tracks your cycle and predicts your PMS window, so you know when the sensitive days are coming. Then, when a hard premenstrual moment comes, you reflect on it, regulate in about a minute, and respond with a clearer head.
Does Niyora track my cycle?
Yes. Niyora tracks your cycle and predicts your PMS window. There is a period calendar and a Smart PMS mode that learns your rhythm after a few logged cycles, so you can see the sensitive window coming. Niyora then goes further than a chart. It shows up in the premenstrual moment itself and walks you through Reflect, Regulate, Respond in about a minute, with training that builds the skill before you need it.
Do I need an account to use Niyora?
No. There is no account and no sign in. You download the app and start using it.
ADHD and perimenopause
Is Niyora only for PMS?
No. When you open Niyora, it asks what brings you here: PMS or PMDD, ADHD, or perimenopause. Moon works the same way for all three. With ADHD or perimenopause, Home shows your feelings by time of day, period logging is optional, and there are no PMS predictions.
Does Niyora diagnose or treat ADHD or perimenopause?
No. Niyora helps in the minute a feeling takes over. It does not diagnose or treat ADHD or perimenopause, and Moon does not advise on medication, supplements or hormone therapy. It points those questions to your doctor.
Privacy
Is my data private?
Yes. There is no account, so there is no profile of you building up over time. Nothing you send is tied to an account. When a moment needs the AI, the app removes email addresses, phone numbers and names it can spot from what you type before it is sent. Privacy is on by default, with no setting to find.
Does Niyora use AI, and can it read my personal details?
Niyora uses AI to help you reflect and respond, but it does not need to know who you are to do that. Before what you type reaches the AI, the app removes email addresses, phone numbers and names it can spot. Places are not removed, and photos and your voice are sent as they are.
