Hormonal contraception
Turn it on in Settings → About you → Right now, with the day it started. Bleeding inside that period is treated as a withdrawal bleed, not as a cycle.
Why it matters
Because a pill-free bleed every 28 days would otherwise turn your range into “28–28 days” and make every comparison afterwards meaningless. With the state on, those bleeds are kept in your calendar and left out of cycle counting.
What still works
Everything else. Symptoms, medications, notes, the summary — all unchanged. The pill itself can be added as a medication if you want its dose history and reminders.
Marking the bleeds
Mark them as usual. In the day sheet you can label one Withdrawal bleed (pill break) or Breakthrough bleeding; the labels describe what happened and do not change any counting.
Stopping it
In Right now, pick what came next — usually Periods on my own — with the day it began; the contraception record closes the day before. The app asks — optionally — why you stopped: side effects, planning a pregnancy, cost, your clinician's decision, or something else. It also asks what you noticed on it. It is your answer, kept as you gave it, and the app draws nothing from it.
The first cycle after stopping starts with your next period. Cycles that straddle the change are left out of your range, because half of one is not a cycle.
