A couple of minutes of small steps and it gets clearer: wait, take a test or talk to a clinician. Personal questions can be skipped — "I'd rather not say" is an answer too. A pointer, not a diagnosis.
How many days late are you?
A cycle is alive: it can shift with what's going on in your life. Let's look at that first.
How were the last month or two — calm, or a lot of stress?
And has your body been through anything: illness, a sharp weight change, unusually hard training, long travel?
Have delays been repeating — several cycles in a row?
Hormonal contraception is a common reason: on some kinds periods get rare or stop altogether.
Are you using hormonal contraception?
Next — about a possible pregnancy. If you've already taken a test, there'll be no extra questions.
Have you taken a pregnancy test?
I'm only asking to figure out whether a test makes sense.
Have you had sex with a partner this cycle?
Slip-ups happen to everyone — no judgement here, just helping you get your bearings.
Did you use protection?
Two short questions about how you feel — they matter when pregnancy is possible.
Do you have severe lower-belly pain right now?
Any spotting that doesn't look like your usual period?
needs medical help soon
Please seek care today
Pain or spotting with a possible pregnancy can't be handled by an app — this is when you call a clinician right away, out of care.
What you can do
- Contact a doctor or urgent care now
- Don't wait it out or postpone until tomorrow
- Bring your cycle dates — they're in your HeySis calendar
worth seeing a doctor
Worth checking, not just waiting
By your answers, this delay is better not left alone. Not "something scary" — just a couple of clear steps.
What you can do
- If pregnancy is possible and you haven't tested — do it in the morning, it's more reliable
- A positive test, a delay over two weeks or repeats cycle after cycle are a reason to book a gynecologist
- Show the doctor your HeySis cycle calendar — it makes the visit quicker and clearer
nothing worrying here
Looks like you can safely wait
Short delays are often explained by stress, sleep, illness or travel — a cycle is alive and allowed to shift.
What you can do
- If pregnancy is possible, take a test from the first day your period is late. If you don't know when your period is due, take it 21 days after sex without reliable protection
- If your test was negative and no period yet — repeat it in 3–4 days, in the morning
- Keep logging days in HeySis to see the pattern
- Be kind to yourself: sleep, food, less stress
This is a hint, not a diagnosis. If you're unsure, a doctor will know best.
